Calculate the standard enthalpy of formation of ethanoic acid given that the standard enthalpy of combustion for carbon is –394 kj mol-1 , hydrogen is –286 kj mol-1 and ethanoic acid is –876 kj mol-1

Explanation:

given,

enthalpy of combustion of carbon = –394 kJ mol-1

enthalpy of combustion of hydrogen = –286 kJ mol-1

enthalpy of combustion of ethanoic acid = –876 kJ mol-1
