Question

Describe catalyst and its function. Check all that apply. A catalyst is a substance that is not used up during a reaction. A catalyst affects the products obtained in the reaction. A catalyst does not change the pathway of the reactants to products in a way that reduces the activation energy and lowers the speed of the reaction. A catalyst does not affect the products obtained in the reaction. A catalyst changes the pathway of the reactants to products in a way that reduces the activation energy and speeds up the reaction. A catalyst is a substance that is used up during a reaction.

Answer 1

A catalyst is a substance that is not used up during a reaction.

The definition of a catalyst is that it speeds up the reaction and is not chemically changed so it is not used up during the reaction.

A catalyst does not affect the products obtained in the reaction.

It only affects the rate of reaction, not the product.

A catalyst changes the pathway of the reactants to products in a way that reduces the activation energy and speeds up the reaction.
