The most effective way to increase the rate of reaction is to increase the temperature. This is effective up to a certain temperature (depending on the specific reaction and enzyme). Above that point the reaction may slow down (drastically) or stop entirely. Note that enzymes speed up a chemical reaction by physically binding with a substrate (or substrates) and causing the appropriate change (breaking apart a large molecule into two or more pieces, combining two substrates into one molecule, etc.) A substrate is a material (chemical, element, compound, whatever) that is undergoing a reaction. It is changed by the reaction. If the materials that are reacting are heated past an enzyme's tolerance, the enzyme undergoes what is known as "denaturation." This means that the molecule physically alters, losing the specific shape that allows it to function as an enzyme. As a reminder, heat is defined as random kinetic energy. That is, heat causes atoms, molecules, proteins, etc. to move around in a random fashion. Heat can speed up a reaction because it moves around the substrate and enzyme molecules faster, allowing them to "bump into" each other more often. By the same token, this random movement will, if great enough, shake up a molecule so much that molecule falls apart or alters in some way. High heat denatures the molecule. Another technique is to increase the amount of substrate and/or enzyme. Increasing the substrate or enzyme increases the rate of reaction because the two materials will bump into each other more quickly and frequently.
You can increase the rate of a chemical reaction by increasing the temperature, which provides more energy for reactions to occur, or by adding a catalyst that lowers the activation energy barrier for the reaction.
One way to increase the activity of an enzyme is to alter the temperature, to bring it nearer to the optimum for that enzyme.
Another is to adjust the pH, likewise to approach the optimum.
If there is very little of the enzyme present, increasing the enzyme concentration will also accelerate the overall process.
Take for instance you have added an irreversible inhibitor to a sample of enzyme and substrate, the reaction will stop completely. thus the enzyme is inactive at this point the way to regain the activity of this enzyme is to add new enzyme. Because they bind directly to the active site by covalent bonds, irreversibleinhibitors permanently render an enzyme inactive. Some drugs are irreversible inhibitors, including the antibiotic penicillin (which inhibits an enzyme involved in bacterial cell-wall synthesis) and aspirin (which inhibits cyclooxygenase-2, the enzyme involved in the inflammatory reaction).
Enzymes have temperature and pH range in which they function optimally.
If you change the temperature and pH so that they are at the optimal point - this will speed up the enzyme's activity.
First by latching onto the specific pair of substrate molecules that all, each, any and every enzyme is attuned to, it brings them into close proximity thereby lowering the Activation Energy of the chemical reaction involved below its 'usual' level.
In the Cell, enzymes provide 100% yield while reacting, this means that there are no useless by-products to clog 'things' up, and this alone speeds up all of the other cellular activities.
By altering the temperature to bring the enzyme closer to it's optimal temperature. Also, by altering the pH to bring the enzyme closer to it's optimal pH.

How does the catalyst and inhibitors affect the rate of chemical reaction?
Catalysts increase the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. Inhibitors, on the other hand, decrease the rate of a reaction by interfering with the reaction mechanism, often by binding to the enzyme or substrate and preventing the reaction from taking place.
What are two ways that chemical reaction between substances affect chemical bonds?
3j
What ways can a catalyst affect a chemical reation?
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
What three ways would let you know that a reaction of a metal had taken place?
Observation of a change in the appearance of the metal, such as discoloration or formation of a patina. Production of bubbles or gas, indicating a chemical reaction is occurring. Increase in temperature or release of heat during the reaction.
How is a reaction rate measured experimentally?
There are two ways people can measure the rate of reaction. People can measure how quickly the reactants are used up as they react to make products. Or people can measure the rate at which the products of the reaction are made.
What are Ways to change the rate of a chemical reaction?
1. Increase the temp 2. Increase surface area 3. Increase the pressure of the system
What methods can you use to increase the rate of a chemical reaction?
There are several ways that the rate of reaction may be increased. Some of the more common ways areincrease temperatureincrease surface area (grind or powder the reactants)use a catalystagitate/stir the reaction mixture
What are three ways to increase the rate at which particular reaction proceeds?
Increase the temperature: Higher temperatures typically increase the rate of reaction by providing reactant molecules with more kinetic energy to overcome activation energy barriers. Add a catalyst: Catalysts provide an alternative reaction pathway with lower activation energy, allowing the reaction to proceed faster without being consumed in the process. Increase the concentration of reactants: Higher concentrations of reactants increase the frequency of collisions between molecules, which can lead to more successful collisions and a higher reaction rate.
What is a combustion reaction describe two ways in which you could increase the route of a combustion reaction?
A combustion reaction is a type of chemical reaction that involves the rapid combination of a fuel with oxygen, producing heat and light. Two ways to increase the rate of a combustion reaction are increasing the concentration of oxygen, which provides more reactant for the reaction, and increasing the temperature, which provides more kinetic energy to the molecules, leading to more collisions and increased reaction rate.
How does the catalyst and inhibitors affect the rate of chemical reaction?
Catalysts increase the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. Inhibitors, on the other hand, decrease the rate of a reaction by interfering with the reaction mechanism, often by binding to the enzyme or substrate and preventing the reaction from taking place.
Describe the ways in which the rate of a chemical reaction can be changed?
The rate of a chemical reaction can be changed by altering the temperature, concentration of reactants, presence of catalysts, and the surface area of the reactants. Increasing the temperature generally increases the rate of reaction, while higher concentrations of reactants and the use of catalysts can also speed up the reaction. Increasing the surface area of the reactants can also increase the rate of reaction by providing more contact points for the reaction to occur.
What speeds up in chemical reaction?
In a chemical reaction, the rate of reaction can be sped up by increasing the temperature, concentration of reactants, or pressure for gases. The use of catalysts can also accelerate the reaction by lowering the activation energy required for the reaction to occur.
What are two ways the rate of chemical reaction can be changed?
The rate of a chemical reaction can be changed by altering the temperature, as reactions generally proceed faster at higher temperatures due to increased kinetic energy. Another way to change the rate of a chemical reaction is by altering the concentration of reactants, where increasing the concentration typically leads to a faster reaction rate due to more frequent collisions between reactant molecules.
What are the three ways discussed in our lessons that chemists can control the rates of chemical reactions?
The reaction rate is dependet on temperature, pressure and reactants concentration.
What other two ways of increasing rates of reaction?
Increasing the concentration of reactants: This provides more opportunities for collisions between particles, which can lead to an increased rate of reaction. Increasing the temperature: Higher temperatures can increase the kinetic energy of particles, resulting in more frequent and energetic collisions, thus speeding up the reaction rate.
