For complete combustion of ethanol , $\;C_{2}H_{5}OH(l)+3O_{2}(g)\to 2CO_{2}(g)+3H_{2}O(l) \;$, the amount of heat produced as measured in bomb calorimeter is ,1364.47 $\;kJmol^{-1}\;$ at $\;25^{0}C\;$.Assuming ideality the Enthalpy of combustion , $\bigtriangleup_{c}H\;$,for the reaction will be : $\;(R=8.314 kJmol^{-1})\;$

$(a)\;-1366.95 kJmol^{-1} \qquad(b)\; -1361.95 kJmol^{-1}\qquad(c)\;-1460.50 kJmol^{-1}\qquad(d)\;-1350.50 kJmol^{-1}$
