Answer to Question #112383 in General Chemistry for lainee

Question

5 br + bro3 + 6h+ -> 3 br2 + H2o expression rates with the dissapreance of br, bro3, and the formation of br2. what are the stoichiometry relationships?

Answer 1

Rate= k[BrO₃^-][Br^-][H⁺]²

The order is the exponent for each reactant, so it is first order with respect to bromate and bromide abd second order with respect to hydrogen ion. the overall order is the sum of the individual orders, which makes this reaction fourth order.
