Question

A catalyst accelerates a reaction because:_____.
a. it increases the number of collisions between molecules.
b. it increases the number of molecules with energy equal to or greater than the activation energy.
c. it supplies energy to reactant molecules.
d. it lowers the activation energy for the reaction.
e. it increases the temperature of the molecules in the reaction.

Answer 1

Answer:

D. Lowering activation energy for the reaction

Explanation:

Catalysts increase the rate of a reaction without being used up. They do this by lowering the activation energy needed. With a catalyst, more collisions result in a reaction, so the rate of reaction increases.
