Chemical Thermodynamics: JEE Main 2014 Chemistry question

For complete combustion of ethanol, C₂H₅OH(l) + 3O₂(g) $\to$ 2CO₂(g) + 3H₂O(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)
