What is the rate law for the following mechanism?
N₂O + NO → N₂ONO (Slow)
N₂ONO → N₂ + NO₂ (Fast)

Question

What is the rate law for the following mechanism? N₂O + NO → N₂ONO (Slow) N₂ONO → N₂ + NO₂ (Fast)

Quizplus · Accepted Answer

The rate law is determined by the slow step, which is the first step in this mechanism. The reactant in the slow step is N₂O, so the rate law must include this reactant. The coefficient in front of N₂O in the balanced equation is 1, and there is no other reactant involved in the slow step, so the rate law must be Rate = k[N₂O][NO].
