For complete combustion of ethanol, ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{l}\right)+3{\mathrm{O}}_2\left(\mathrm{g}\right)⟶{\mathrm{CO}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$, the heat produced as measured in bomb calorimeter, is  $1364.47\mathrm{kJ}{\mathrm{mol}}^{-1}$ at 25°C. Assuming ideality the enthlapy of combustion, ${\mathrm{\Delta }}_{\mathrm{c}}H,$ for the reaction will be $\left(R=8.314{\mathrm{JK}}^{-1}{\mathrm{mol}}^{-1}\right)$
