    Under what condition, the heat evolved or absorbed in a reaction is equal to its free energy change?

    Answer:

                  As \[\Delta G=\Delta H-T\Delta S\]. Thus, \[\Delta G=\Delta H\] only when either the reaction is carried out at 0°K or the reaction is not accompanied by any entropy change, i.e., \[\Delta S=0\].
