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