Step 1:H2O2 + I^-^ = H2O + OI^-^

step 2: H2O2 + OI^-^ = H2O + O2 + I^-^

What is the equation for the overall reaction? I am not sure how to do this since there are two equations.

Complete the rate law for the overall reaction. I know how to do this one but I am not sure of the equation for the first question.
