Calculate the standard enthalpy change of formation, \( \Delta H^{\ominus}_{f} \), in \( kJ~mol^{-1} \), of ethyl ethanoate, \( C_{4}H_{8}O_{2} \) Use sections 1 and 13 of the data booklet and the value of \( -4~kJ~mol^{-1} \) for the standard enthalpy change of reaction, \( \Delta H^{\ominus}_{r} \).
