The following mechanism has been proposed for the decomposition of hydrogen peroxide using potassium bromide: Step 1: H2O2 (aq) + Br- (aq) > H2O (aq) + OBr- (aq) (Slow) Step 2: H2O2 (aq) + OBr- (aq) > H2O (aq) + Br- (aq) + O2 (g) (Fast) Overall: 2H2O2 (aq) > 2H2O (aq) + O2 (g) The predicted rate law for this reaction is: A.Rate = k[H2O2][OBr-] B.Rate = k[H2O2]2 C.Rate = k[H2O2]2[Br-] D.Rate = k[H2O2][Br-] E.Rate = k[H2O2][OBr-]
