This problem has been solved! See the answer The oxidation of Br^- by BrO3^- in acidic solution is described by the equation 5Br^- (aq) + BrO3^- (aq) + 6H^+ (aq) = 3Br2 (aq) + 3H2O (l) The reaction is first order in Br^-, first order in BrO3^-, and second order in H^+.

A) write the rate law
B)what is the overall reaction order?
C) How does the reaction rate change if the H+ concentration is tripled?
D) What is the change in rate if the concentration of both Br and BrO3 are halved?
