Question

Adding a catalyst to a chemical reaction results in which of the following?

a. An INCREASE in activation energy and a DECREASE in the reaction rate.

b. An INCREASE in activation energy and an INCREASE in the reaction rate.

c. A DECREASE in activation energy and a DECREASE in the reaction rate.

d. A DECREASE in activation energy and an INCREASE in the reaction rate.

Explain your answer.

Answer 1

Decrease in activation energy and increase in reaction rate
As it doesn’t effect equilibrium position it only increases rate of both forward and backward by same rate
