A) \[-8\text{ }kJ\text{ }mo{{l}^{-1}}\]
B) \[+8\text{ }kJ\text{ }mo{{l}^{-1}}\]
C) \[-5748\text{ }kJ\text{ }mo{{l}^{-1}}\]
D) \[+5748\text{ }kJ\text{ }mo{{l}^{-1}}\]
Correct Answer: A
Solution :
[a] \[Isobutane+oxygen\to C{{O}_{2}}+{{H}_{2}}O\] \[\Delta H=-2870\,kJmo{{l}^{-1}}\] ......(i) \[n-butane+oxygen\to C{{O}_{2}}+{{H}_{2}}O\] \[\Delta H=-2878\,kJmo{{l}^{-1}}\] ....(ii) (iii) (i); n-butane - Isobutane, \[\Delta H=\left( -2878+2870 \right)\] \[=-8\,kJmo{{l}^{-1}}\].You need to login to perform this action.
