Chemistry

Given the following heats of formation (ΔH°f, 25°C)and heats of combustion (ΔH°c, 25°C) data, determine theheat of reaction for the liquid-phase esterification of lactic acid(C3H6O3) with ethanol(C2H5OH) to form ethyl lactate(C5H10O3) and liquid water at 25°Cand 1 atm.

C3H6O3 +C2H5OH -->C5H10O3 + H2O(liquid)

The table below shows the standard heat of combustion and heatof reaction.
