A) \[-128.02\,kJ\,mo{{l}^{-1}}\]
B) \[+12.802\,kJ\,mo{{l}^{-1}}\]
C) \[+128.02\,kJ\,mo{{l}^{-1}}\]
D) \[-12.802\,kJ\,mo{{l}^{-1}}\]
Correct Answer: C
Solution :
\[C+2S\to C{{S}_{2}}\,\,\,\,\Delta H=?\] \[C+{{O}_{2}}\to C{{O}_{2}}\,\,\,\,\Delta H=-393.3\,\,kJ\] ?.(i) \[S+{{O}_{2}}\to S{{O}_{2}}\,\,\,\,\Delta H=-293.72\,\,kJ\] ?..(ii) \[C{{S}_{2}}+3{{O}_{2}}\to C{{O}_{2}}+2S{{O}_{2}}\,\,\,\,\Delta H=-1108.76\,kJ\] ?..(iii) eq. (ii) × 2 + eq. (i) ? (iv) eq. (iii) ? eq. (iv) and find required result .
