17. Solution to Chemistry Problem

20. The heat effects of the following reactions are known
CH3COOC2H5(l) OH-(aq)=CH3COO-(aq) C2H5OH(l)
ΔrH0298=-54.7 kJ*mol-1
CH3COOH(l) OH-(aq)=CH3COO-(aq) H2O(l)
ΔrH0298=-57.3 kJ*mol-1
CH3COOC2H5(l) 2H2(g)= C2H5OH(l)
ΔrH0298=-74.6 kJ*mol-1
Calculate the heat effect of the reaction:
C2H5OH(l) O2(g)= CH3COOH(l) H2O(l)
if the enthalpy of formation of liquid water is -285.8 kJ*mol-1
