The following mechanism has been proposed for the reaction of NO with Br2 to form NOBr,
\(\begin{array}{l} \mathrm{NO}(\mathrm{~g})+\mathrm{Br}_{2}(\mathrm{~g}) \rightleftharpoons \mathrm{NOBr}_{2}(\mathrm{~g}) \\ \mathrm{NOBr}_{2}(\mathrm{~g})+\mathrm{NO}(\mathrm{~g}) \rightarrow 2 \mathrm{NOBr}(\mathrm{~g}) \end{array}\)
If the second step is the rate determining step, the order of the reaction with respect to NO(g) is:
- 1
- 0
- 3
- 2
Answer
(A) 1
