Rates of Non-elementary reactions Consider the following mechanism: a. What is the net reaction? Class Activity k₁ 2NO N₂02 K-1 k2 N2O2 + Cl2 2 NOCI b. Which of the above species is an intermediate? Why? c. Find the rate of the overall reaction using the steady-state approximation. d. Repeat part (c) using the rate-determining step method, assuming the first-step is fast and at equilibrium and the second step is slow. 2NO N2O2 (fast, at equilibrium) k-1 k2 N20₂+ Cl22 NOCI (slow) e. At what conditions the rate laws predicted by the steady-state approximation and by the rate-determining step become identical.
