A) \[-504\]
B) \[-142.5\]
C) \[-283\]
D) \[504\]
Correct Answer: C
Solution :
\[C+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}CO,\,\,\Delta H=-110\,\,kJ\,\,mo{{l}^{-1}}\]? (i) \[C+{{O}_{2}}\xrightarrow{{}}C{{O}_{2}},\,\,\Delta H=-393\,\,kJ\,\,mo{{l}^{-1}}\] ... (ii) On subtracting Eq (i) from eq (ii), 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.
