Question

What is the rate law for the reaction NO₂(g) + CO(g) → NO(g) + CO₂(g) if the reaction occurs in the following steps?[(i) NO₂ + NO₂ → NO₃ + NO (slow) (ii) NO₃ + CO → NO₂ + CO₂ (fast)]What is the role of NO₃?

Answer 1

NO3 is an oxidizing agent in the above reaction.

I hope this will help you

Answer 2

Prompt: What is the rate law for the reaction NO₂(g) + CO(g) → NO(g) + CO₂(g) if the reaction occurs in the following steps?[(i) NO₂ + NO₂ → NO₃ + NO (slow) (ii) NO₃ + CO → NO₂ + CO₂ (fast)]What is the role of NO₃?

Answer: Mechanism 1

NO2 + NO2 =>NO3 + NO slow

CO + NO3 => CO2 +NO2 fast

Mechanism 2

NO2 + NO2 =>NO3 + NO fast

CO + NO3 => CO2 +NO2 slow
