What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.
What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
How are rates of reaction determine?
Rates of reaction are determined by factors such as concentration of reactants, temperature, presence of a catalyst, and surface area. Increasing the concentration of reactants and temperature generally increases reaction rates, while adding a catalyst can speed up the reaction by providing an alternative pathway with lower activation energy. Additionally, increasing the surface area of the reactants can enhance reaction rates by increasing the number of collisions between particles.
What are the conditions of making polyethene?
Polyethylene is typically made through the polymerization of ethylene monomer molecules. This process involves the use of a catalyst, such as a transition metal complex, at elevated temperatures and pressures. Conditions such as temperature, pressure, catalyst type, and monomer concentration can all affect the properties of the resulting polyethylene.
Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.

What are the 5 important factors that influence the rate of a chemical reaction?
The key factors that influence the rate of a chemical reaction are concentration of reactants, temperature, presence of a catalyst, surface area of reactants, and the nature of the reactants and products.
What are three factors of the speed at which a chemical reaction happens?
temperature presence or absence of a catalyst concentration of reactants
On what does the rate constant depend?
The rate constant depends on factors such as temperature, concentration of reactants, and presence of a catalyst.
What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
Which of these would be expected to increase the rate of sa chemical reaction?
Increasing temperature, increasing concentration of reactants, and adding a catalyst are all factors that can increase the rate of a chemical reaction. This is because they either provide more energy for the reaction to occur (temperature), increase the frequency of reactant collisions (concentration), or lower the activation energy required for the reaction to proceed (catalyst).
How can the spontaneity of a reaction be reversed?
The spontaneity of a reaction can be reversed by changing the conditions such as temperature, pressure, or concentration of reactants, or by adding a catalyst.
How are rates of reaction determine?

What are the factors affecting the states of matter?
Factors affecting states of matter include temperature, pressure, and intermolecular forces. As temperature increases, substances can change from solid to liquid to gas. Pressure can also affect the state of matter, with higher pressure favoring a more condensed state. Intermolecular forces determine how tightly particles are held together in a substance, influencing its state.
