A catalyst changes the mechanism of a reaction

In summary, the conversation is discussing the function of a catalyst and which statement is not correct regarding its effects on a chemical reaction. The options are a. A catalyst lowers the activation energy, b. A catalyst changes the mechanism of the reaction, c. A catalyst affects the rate of the reaction, d. A catalyst lowers the energy of the product, and e. none of these. One person suggests finding out how a catalyst lowers the activation energy, while another person jokingly mentions someone breaking the rules.

I know that this one can't be a. or c. which is true but, i think its either b. or d., does a catalyst change the mechanism of a chemical reaction ?


Which statement is not correct regarding the function of a catalyst?

a. A catalyst lowers the activation energy.
b. A catalyst changes the mechanism of a reaction.
c. A catalyst affects the rate of a chemical reaction.
d. A catalyst lowers the energy of the product, causing the _____reaction to be more exothermic.
e. none of these

Try finding out how a catalyst lowers the activation energy. That should give you the answer.

1. How does a catalyst change the mechanism of a reaction?

A catalyst works by lowering the activation energy of a reaction, making it easier for the reactants to form products. This changes the mechanism of the reaction by providing an alternate pathway with lower energy barriers, allowing the reaction to occur more quickly and efficiently.

2. What is the role of a catalyst in a chemical reaction?

The role of a catalyst is to increase the rate of a chemical reaction by lowering the activation energy. It does this by providing an alternate pathway for the reaction to occur, without being consumed or permanently altered in the process.

3. Can a catalyst change the overall outcome of a reaction?

No, a catalyst does not change the overall outcome of a reaction. It only affects the rate at which the reaction occurs by lowering the activation energy. The reactants and products of the reaction remain the same.

4. Is a catalyst specific to a certain reaction or can it be used for multiple reactions?

A catalyst is specific to a certain reaction or group of reactions. Each catalyst is designed to lower the activation energy of a specific reaction, and may not work for other reactions. However, some catalysts can be used for multiple reactions within a similar type of chemical process.

5. Can a catalyst be used in unlimited amounts?

No, adding more catalyst does not necessarily increase the rate of a reaction indefinitely. There is a limit to how much a catalyst can lower the activation energy, and adding excess amounts may even have a negative effect on the reaction. The amount of catalyst needed depends on the specific reaction and conditions.
