For complete combustion of ethanol, $C_2H_5OH (\ell) + 3O_2 (g) \to 2CO_2 (g) + 3H_2O (\ell)$, the amount of heat produced as measured in bomb calorimeter, is $1364.47\; kJ \;mol^{–1}$ at $25^{\circ}C$. Assuming ideality the Enthalpy of combustion, $\Delta_CH$, for the reaction will be: $(R = 8.314\; kJ \;mol^{–1} )$
( A ) $-1350.50\; kJ\; mol^{-1}$
( B ) $-1460.50\; kJ\; mol^{-1}$
( C ) $-1366.95\; kJ\; mol^{-1}$
( D ) $-1361.95\; kJ\; mol^{-1}$
