For the reaction, OCl^- _(aq) + I^- _(aq) OI^- _(aq) + Cl^- _(aq)

It was determined that the reaction is second order with respect to OCl^- and first order with respect to I^-.

a) Write the corresponding rate law expression.

b) Doubling the concentration of OCl^- would cause the rate of reaction to change by how much?

c) Tripling the concentration of I^- would cause the rate to change by how much?
