  1. Oct 5, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2
    By what factor does the rate change if the concentration of H+ is decreased by a factor of 3? Just put in the number as a whole number or fraction.

    2. Relevant equations

    3. The attempt at a solution
    Isnt the answer 1/8 ?
    2^3 = 8
