For complete combustion of ethanol, C 2 H 5 OH( l ) + 3O 2 (g) → 2CO 2 (g) + 3H 2 O( l ), the amount of heat produced as measured in bomb calorimeter, is 1364.47 kJ mol –1 at 25ºC.. Assuming ideality the Enthalpy of combustion, ∆ C H, for the reaction will be : (R = 8.314 kJ mol –1 )

1. – 1361.95 kJ mol –1
2. – 1460.50 kJ mol –1
3. – 1350.50 kJ mol –1
4. – 1366.95 kJ mol –1

Correct answer: – 1366.95 kJ mol –1
