... Step 2 is rate determining step and this will determine the rate of the reaction. The subsequent step can be ignored in working out the rate. Step 2 involves the decomposition of N2O4 and depends only on its concentration: rate = k2[N2O4(g)] As this involves the concentration of a reaction intermedi ...
