Problem
For the gas-phase decomposition of dinitrogen tetroxide, a proposed mechanism consists of a single elementary step that is rate-determining:
N2O4(g)→2NO2(g)(slow)
Which of the following is the predicted rate law for the overall reaction?
(a) rate = k[\mathrm{NO_2}]^2
(b) rate = k[\mathrm{N_2O_4}]^{1/2}
(c) rate = k[\mathrm{N_2O_4}]
(d) rate = k[\mathrm{N_2O_4}]^2
