1.	In the reaction A^(+) + B rarr A+ B^(+) , there is no entropy change. Enthalpy change, Delta Hequals 22 kJ mol^(-1) of A^(+) . Calculate the DeltaG for the reaction . Under what condition free energy change will have negative value ?
Answer» Solution :`DeltaS= 0, DeltaH = 22kJ mol^(-1)`. H ENCE, `DELTAG = DeltaH - T DeltaS = DeltaH = 22kJ mol^(-1)`.
