Answer
... overall rate equation you would expect to see for this mechanism. If step 1 is at equilibrium, with equilibrium constant, K: K = [N2O2(g)]/[NO(g)]2 [N2O2(g)] = K [NO(g)]2 Step 2 involves the bimolecular reaction of a N2O2 molecule with a Br2 molecule. The rate of this step is therefore: rate = k2[N2 ...
