View SolutionThe reaction of formation of phosgene from $CO$ and $Cl_2$ is $CO + Cl_2 \to COCl_2.$ The proposed mechanism is
$(i)$ $Cl_2 \,\underset{k_2}{\overset{k_1}{\longleftrightarrow}}\, 2Cl$
$(ii)$ $Cl + CO \,\underset{k_4}{\overset{k_3}{\longleftrightarrow}}\, COCl$
$(iii)$ $COCl + Cl_2 \xrightarrow{k_5} COCl_2 + Cl$ (slow)

During the kinetic study of the reaction $2A + B \rightarrow C + D$,the following results were obtained:
Experiment $[A] \ (M), [B] \ (M)$ and Initial rate of formation of $D$ $i. \ [A]=0.1, [B]=0.1$ $6.0 \times 10^{-3} \ M \ s^{-1}$ $ii. \ [A]=0.3, [B]=0.2$ $7.2 \times 10^{-2} \ M \ s^{-1}$ $iii. \ [A]=0.3, [B]=0.4$ $2.88 \times 10^{-1} \ M \ s^{-1}$ $iv. \ [A]=0.4, [B]=0.1$ $2.40 \times 10^{-2} \ M \ s^{-1}$
Based on the above data,the overall order of the reaction is:
| Experiment | $[A] \ (M), [B] \ (M)$ and Initial rate of formation of $D$ |
|---|---|
| $i. \ [A]=0.1, [B]=0.1$ | $6.0 \times 10^{-3} \ M \ s^{-1}$ |
