The possible mechanism for the reaction $2NO + Br_2 \to 2NOBr$ is:
$NO + Br_2 \rightleftharpoons NOBr_2$ (Fast)
$NOBr_2 + NO \to 2NOBr$ (Slow)
The rate law expression is:
$NO + Br_2 \rightleftharpoons NOBr_2$ (Fast)
$NOBr_2 + NO \to 2NOBr$ (Slow)
The rate law expression is:
- A$r = K [NO][Br_2]$
- B$r = K [NO][NOBr_2]^2$
- C$r = K [NO]^2 [Br_2]$
- D$r = K [NOBr_2][NO]^2 [Br_2]$
