A) \[-121\text{ }kJ\] per mol
B) \[+121\text{ }kJ\] per mol
C) \[+242\text{ }kJ\] per mol
D) \[-242\text{ }kJ\] per mol
Correct Answer: A
Solution :
\[\Delta H=?\] \[\Delta H=[\Delta H\]of combustion of cyclohexan\[-(\Delta H\] of combustion of cyclohexene\[+\Delta H\]of combustion of\[{{H}_{2}}\])] \[=-[-3920-(3800-24)]\text{ }kJ\] \[=-[3920+4041]\] \[=-[121]kJ\] \[=-121kJ\]You need to login to perform this action.
