What effect does an increase in products have on the reaction rate of a mixture at equilibrium? a. the forward reaction rate increases. b. both the forward and the reverse reaction rates decrease. c. both the forward and the reverse reaction rates increase. d. the reverse reaction rate increases.

D. The reverse reaction rate increases.

Explanation:

The rate of reverse increases if the products are increased in a mixture at equilibrium.

At first, rate of forward and backward reactions are same for a mixture in equilibrium.

If we add products or,the reaction moves to the opposite side I.e towards reactants side.

so,according to the Le Chateliers principle,the reaction shifts opposite to the side of increase. so,according to the Le Chateliers priciple, the rate of reverse or backward reaction will increase with the increase in the products.

b is the correct
