Select the correct answer. 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.

If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants.

Explanation:

If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants. Or, if we remove reactants from the system, equilibrium will also be shifted to the left

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
