Consider the following reactions, C(s) + O2(g) → CO2(g), \(\Delta\) H = -94\(\text{ kcal}\) 2CO(g) + O2 → 2CO2(g), \(\Delta\) H = -135.2\(\text{ kcal}\) Then, the heat of formation of CO (g) is:
For the reactions \(C + O2 \rightarrow CO2\); \(\, \Delta H = -393 \, \text{kJ} 2Zn + O2 \rightarrow 2ZnO\), \(\, \Delta H = -412 \, \text{kJ}\) \(\text{the correct statement is:}\)
