What else can I help you with?
According to collision theory what best explains how a catalyst increases the reaction rate for a chemical reaction?
A catalyst decreases the threshold energy for a chemical reaction. A catalyst decreases energy required for two particles to react. A catalyst lowers the amount of energy needed to reach the transition state.
Why dry ether used as a catalyst in chemical reactions?
Dry ether is used as a catalyst in some chemical reactions because it can solvate ions and stabilize intermediates which helps facilitate the reaction. It also helps in breaking down some compounds and forming new bonds by providing a medium for the reaction to occur. Additionally, it can act as a nucleophile in some reactions due to the presence of lone pair electrons.
What are the similarities and difference between enzymes and chemical catalyst?
so the similarity is that they both speed up the reaction and both have special temperatures they best work at the only difference between them is that enzymes are found in humans and are not made by humans on particular purpose,whereas chemical catalysts are made by people and are not naturaly developed
Does acetone function as a catalyst?
As most catalysts are quite specific in the (or at least the type of) reaction, in others not working at all, I can't give an answer for 'your acetone-reaction'. But to my best knowledge there are very few reactions I can think of being catalysed by acetone; never heard of, you know.
What is catalyst severity?
A catalyst is something which speeds up a chemical reaction without itself being one of the reactants or products (in other words, without being consumed). Magnesium sulfate is probably a good catalyst for some reactions, not for others. What reaction are you interested in? Best, Prof. Topper ========================================================== A catalyst is a substance that accelerates a chemical reaction without being changed by the reaction. Different substances catalyze different reactions. For example, platinum catalyzes the burning of hydrogen in air, acid catalyzes the decomposition of starch into glucose, and iron catalyzes the decomposition of hydrogen peroxide into water and oxygen. I do not know of any reaction that is catalyzed by magnesium sulfate, so I don't know why it might be a good catalyst. by Robert john at the aveland high school 11ad head of science teacher s.dancey 26th September 2008

How can you change the rate of chemical change in a substance?
This is a very vague question and would depend on the chemical that you are talking about. The easiest way I can think to explain it on a wide variety of chemicals is by using a catalyst (speeds up the process of a chemical reaction), or the use of an antagonist (Slows a chemical reaction). I hope this helps, but without any specific chemicals being named this is the best i can do. :) By heating we can change the rate of chemical change(reaction).

What is a statement that best describes an enzyme?
Enzymes are biological molecules that act as catalysts to increase the rate of chemical reactions in living organisms by lowering the activation energy needed for the reaction to occur. They are specific in their function and often end in "-ase".
Which statement best explains how enzymes speed up chemical reactions?
Enzymes speed up chemical reactions by lowering the activation energy needed for the reaction to occur. This allows the reaction to happen more quickly, as enzymes provide an alternative pathway with a lower energy barrier for the reaction to proceed. Ultimately, enzymes help substrates to reach the transition state more easily, facilitating the reaction.
What type of chemical reaction do glow sticks best represent?
Glow sticks best represent a chemical reaction known as chemiluminescence, where light is produced as a result of a chemical reaction without the need for heat.
Is copper sulphate the best catalyst between zinc and hydrochloric acid?
Copper sulfate is not typically used as a catalyst in the reaction between zinc and hydrochloric acid. The reaction between zinc and hydrochloric acid is a single displacement reaction where zinc displaces hydrogen from hydrochloric acid to form zinc chloride and hydrogen gas. In this reaction, the presence of copper sulfate would not act as a catalyst to speed up the reaction.
How can activation energy be reduced?
Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of reaction.
Which statement best describes the use of a catalyst in a fuel cell?
A catalyst in a fuel cell speeds up the chemical reactions that convert fuel and oxygen into electricity, without being consumed in the process. It lowers the activation energy required for the reactions to occur, increasing the efficiency of the fuel cell.
