| \[{{H}_{2}}\left( g \right)+2ICl\left( g \right)\to 2HCl\left( g \right)+{{I}_{2}}(g)\] |
| This reaction is first order in \[{{H}_{2}}\] (g) and also first order in ICl(g). Which of these proposed mechanism can be consistent with the given information about this reaction? |
| Mechanism I: |
| \[{{H}_{2}}\left( g \right)+2ICl\left( g \right)\to 2HCl\left( g \right)+{{I}_{2}}\left( g \right)\] |
| Mechanism II: |
| \[{{H}_{2}}(g)+ICl(g)\xrightarrow{Slow}\,\,HCl(g)+HI(g)\] |
| \[HI(g)+ICl(g)\,\,\xrightarrow{fast}\,\,HCl(g)+{{I}_{2}}(g)\] |
A) I only
B) II only
C) both I and II
D) neither I nor II
Correct Answer: B
Solution :
\[I{{I}^{nd}}\] mechanism is favoured because according rate expression one \[{{H}_{2}}\] & one \[IC\ell \] is involved in rate determining step
