1.	Under what condition, the heat evolved or absorbed in a reaction is equal to its free energy change ?.
Answer» Solution :`H_2O_((s)) HARR H_2O_((l)) Delta_"FUS"`H is 6 kJ `"MOL"^(-1)` (a)`DeltaG=DeltaH-TDeltaS` When the reaction is carried out at `0^@`K or `DeltaS=0` `DeltaG=DeltaH` (b)`H_2O_((s)) hArr H_2O_((l))` `Delta_"fus"H ="6 kJ mol"^(-1)` `=6000 "J mol"^(-1)` `Delta_"fus"H ="6 kJ mol"^(-1)` `=6000 "J mol"^(-1)`
