The Acid-Catalyzed Reaction of Acetone,CH₃COCH₃,with Iodine Can Be Represented by the Following

question 63

Multiple Choice

The acid-catalyzed reaction of acetone,CH₃COCH₃,with iodine can be represented by the following net reaction:
CH₃COCH₃ + I₂
CH₂ICOCH₃ + H⁺ + I^-
It is found experimentally that the rate law for this reaction is Rate = k[CH₃COCH₃][H⁺].Suppose that in trial 1,the initial rate of the reaction is measured with the initial concentrations of acetone,iodine,and hydrogen ion all equal to 0.10 M.Then,in trial 2,the initial rate of the reaction is measured with the initial concentrations all equal to 0.20 M.The initial rate of trial 2 will be larger than the initial rate of trial 1 by a factor of

• A)4.
• B)16.
• C)8.
• D)2.
• E)64.
