A) \[-504\]
B) \[-142.5\]
C) \[-283\]
D) 504
Correct Answer: C
Solution :
\[C+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}CO,\Delta H=-110\,kJ\,mo{{l}^{-1}}\] ....(1) \[C+{{O}_{2}}\xrightarrow{{}}C{{O}_{2}},\Delta H =-393\,kJ\,mo{{l}^{-1}}\] ......(2) On subtracting eq. (1) from eq. (2), we get \[CO+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}C{{O}_{2}}\] \[\Delta H =(-393)-(-110)\] \[=-283\,kJ\,mo{{l}^{-1}}\]You need to login to perform this action.
