In Aqueous Solution,iodine Reacts with Acetone as Represented by the Following

In aqueous solution,iodine reacts with acetone as represented by the following equation:
I₂(aq) + CH₃COCH₃(aq) → CH₃COCH₂I(aq) + H⁺(aq) + I^-(aq)
The experimental rate law is Rate = k[H⁺][CH₃COCH₃].According to the information above,an increase in the hydrogen ion concentration has what effect on the reaction?

A) It decreases the rate of the reaction.
B) It increases the rate of the reaction.
C) It decreases the value of the equilibrium constant.
D) It increases the value of the equilibrium constant.
E) It does not affect the rate of the reaction.
