| The reaction of hydrogen and iodine monochloride is given as: [AIPMT (S) 2007] |
| \[{{H}_{2}}(g)+2ICl(g)\xrightarrow{{}}2HCl(g)+{{I}_{2}}(g)\] |
| This reaction is of first order with respect to \[{{H}_{2}}(g)\] and \[ICl(g),\] following mechanisms were proposed: |
| Mechanism A: \[{{H}_{2}}(g)+2ICl(g)\xrightarrow{{}}2HCl(g)+{{I}_{2}}(g)\] |
| Mechanism B: \[{{H}_{2}}(g)+ICl(g)\xrightarrow{{}}HCl(g)+HI(g)\]; show |
| \[HI(g)+ICl(g)\xrightarrow{{}}HCl(g)+{{I}_{2}}(g)\]; fast |
| Which of the above mechanism (s) can be consistent with the given information about the reaction? |
A) B only
B) A and B both
C) Neither A nor B
D) A only
Correct Answer: B
Solution :
| [b] Rate of reaction is always depends on slow reaction. |
| \[{{H}_{2}}(g)+2ICl(g)\xrightarrow[{}]{{}}2HCl(g)+{{I}_{2}}(g)\] is first order reaction respect to H2 and I2 can be measured with the help of both mechanism A and B. |
