Homework Answers
Ans 2 : a) Rate = k[BrO3-]2 [H+]12
The rate law expression for the reaction is given as the product of concentration of the reactant species each raised to the power of their stoichiometric coefficients .
The k denotes the rate constant of the reaction.
So the rate law for the reaction is coreectly depicted in option a.
