Question

Quizplus · Accepted Answer

The first step involves two molecules, NO₂(g) and F₂(g), making it bimolecular (molecularity = 2). F(g) is produced in the first step and consumed in the second, making it an intermediate.

Consider the Mechanism NO2(g)+ F2(g) →\rightarrow→ NO2F(g)+ F(g) K1 (Slow) F(g)+ NO2(g)

Consider the Mechanism
NO₂(g)+ F₂(g) $\rightarrow$ NO₂F(g)+ F(g) K₁ (Slow)
F(g)+ NO₂(g)
