Consider the reaction: H2SeO3(aq) + 6 I-(aq)+ 4H+(aq) --> Se(s) + 2 I3- (aq) + 3 H2O ( l)

a) Write t he rate expression – the equation that defines rate in terms of change of concentrations for H2SeO3, I- and I3- .

b.) If the experimentally determined rate law for this reaction that given below, what is the order of the reaction with respect to H2SeO3? to I-? to H+? What is the overall order of thereaction?

Rate = k[H2SeO3] [I-]2 [H+]2.

H2SeO3 order:____________ I-order:______________ H+order:_______________ overall order:_________________
