${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(g)$ is $\Delta {H_1}$ and that of
${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(l)$ is $\Delta {H_2}$. Then
$C_2H_5OH_{(l)}+{3O_2} _{(g)} \rightarrow 2{CO_2} _{(g)}+3{H_2O}_{(l)}$
the amount of heat produced as measured in bomb calorimeter, is $1364.47\, kJ\, mol^{-1}$ at $25\,^oC.$ Assuming ideality the enthalpy of combustion, $\Delta_CH,$ for the reaction will be : $(R = 8.314\,kJ \,mol^{-1})$ .....$kJ\, mol^{-1}$
