11. Nitrogen dioxide and carbon monoxide react according to the following equation:
NO₂(g) + CO(g) ⇌ NO(g) + CO₂(g) ΔH= −226 kJ

(b) The following mechanism is proposed for the reaction. Identify the rate-determining step. (2 points) Step 1: NO₂(g) + NO₂(g) → NO(g) + NO₃(g)
Step 2: NO₃(g) + CO(g) →NO₂(g) + CO₂(g)
