In bomb calorimeter .5f of C2H5OH (M= 46.07 g/mol) was combusted by the reaction below. If the temperature rose by 3.274 C and the foal heat capacity of the apparatus (bomb plus water) was 4.5 J/C determine the change in internal energy in kJ/mol for one mole of the reaction.
C2H5OH (liq) + 3O = 2CO2 (g) + 3H2O (liq)
