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 generally used as solvent in chemical reactions. to the best of my knowledge there is no reaction where ether is used as a catalyst.
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
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 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 explains how enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
What is a statement that best describes an enzyme?
An enzyme is a chemical produced by a living organism which acts as a catalyst in a biochemical reaction.

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).
Which statement best describes the use of a catalyst in a fuel cell?
It increases reaction rates

Best explains how enzymes speed up chemical reactions?
Enzymes speed up the chemical reactions by forcing the reactant molecules into their correct orientation. The enzymes also lower the required energy for collision to produce a 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.
Is copper sulphate the best catalyst between zinc and hydrochloric acid?
Is aqueous copper (2)sulphate an effective catalyst in the reaction between zinc and hydrochloric acid.
What is the best term to describe a chemical reaction that absorbs heat energy?
An endothermic reaction.
