From the stoichometry of the reaction 2I^-(aq) H2O2(aq) 2 H3O^ -->I2(s) 4 H2O(I) the rate law is(multiplechoic

Question

a)is predicted to be third order overal

b)is predicted to be first order in I2(s)

c)is predcited to be first order in all reactants

d)fifth order overall

Answer 1

if this is the rate determining step:

2I^- &  1 H2O2 & 1  H3O^ -->I2(s) 4 H2O(I)

then it is  a fifth order reaction

Your answer is: d)fifth order overall
