The heat of formation of ethanol (C2H5OH) is 277 kJ/mol at 298.

The heat of formation of ethanol (C2H5OH)is 277 kJ/mol at 298.15 K. Calculate the heatof combustion of one mole of ethanol from theinformation given below, assuming that theproducts are CO2(g) and H2O(ℓ).C2H5OH −→ 2 C + 3 H2 +12O2∆H = 277 kJ/molC + O2 −→ CO2∆H = −393.5 kJ/molH2 +12O2 −→ H2O∆H = −29.4 kJ/mol
