When determining the overall rate law for a reaction, the slowest step is the step that determines the reaction rate. Because the first step (in the...

iodate and bisulfite: IO−3 + 3 HSO−3 → I− + 3 HSO−4 This first step is the rate determining step. Next, the iodate in excess will oxidize the iodide generated...

evidence points to reaction 2 as being slow, rate-determining step. This is not unexpected, since that step breaks the nitrogen triple bond, the strongest...
