Question

The following mechanism has been proposed for the reaction of NO₂ with F₂ to form NO₂F:

\[\ce{NO2_{(g)} + F2_{(g)} -> NO2F_{(g)} + F_{(g)} (slow)}\]

\[\ce{F_{(g)} + NO2_{(g)} -> NO2F_{(g)} (fast)}\]

The order of the reaction with respect to NO_2(g)

Options

• 0

• 3

• 2

• 1

Answer 1

1

Explanation:

The first step is the rate determining step because it is slow. The rate low is

rate = k [NO₂] [F₂]

As a result, the reaction order in relation to NO_2(g) is 1.
