320532 Mechanism of a hypothetical reaction
\(\mathrm{X}_{2}+\mathrm{Y}_{2} \rightarrow 2 \mathrm{XY} \text { is given below : }\)
(i) \(\mathrm{X}_{2} \rightleftharpoons \mathrm{X}+\mathrm{X}\) (fast)

(ii) \(\mathrm{X}+\mathrm{Y}_{2} \rightarrow \mathrm{XY}+\mathrm{Y}\) (slow)
(iii) \(\mathrm{X}+\mathrm{Y} \rightarrow \mathrm{XY}\) (fast)
The overall order of the reaction will be :

\(\mathrm{NOBr}_{2}+\mathrm{NO} \rightarrow 2 \mathrm{NOBr}\) (slow)

The order of reaction w.r.t. to \(\mathrm{NO}\) is

320534 Assertion :
In \({\text{A}}\xrightarrow{{{{\text{k}}_{\text{1}}}}}{\text{B}}\xrightarrow{{{{\text{k}}_{\text{2}}}}}{\text{C}}\) If half-life of A is very less as compared to B, so the net reaction is \({\rm{A}} \to {\rm{C}}\) with rate constant \(\left( {{{\rm{k}}_{\rm{1}}}{\rm{ \times }}{{\rm{k}}_{\rm{2}}}} \right)\)
Reason :
Slowest step is the rate determining step so \({\rm{B}} \to {\rm{C}}\) is rate determining step.
