A) \[+26.4\,kcal\]
B) \[-67.6\,kcal\]
C) \[-120.6\,kcal\]
D) \[+52.8\,kcal\]
Correct Answer: B
Solution :
Aim: \[CO+\frac{1}{2}{{O}_{2}}\to C{{O}_{2}}\] \[\Delta H=\Delta H_{f}^{0}\,(C{{O}_{2}})-\left[ \Delta H_{f}^{0}(CO)+\frac{1}{2}\Delta H_{f}^{0}({{O}_{2}}) \right]\] \[=-\,94.0-(-26.4)=-67.6\,\,kcal.\]
