For reaction Ag_(2)O(s)rarr2Ag(s)+(1//2)O_(2)(g) the value of DeltaH=30.56 " kJ mol"^(-1) and DeltaS = 0.066 kJK^(-1)mol^(-1). Temperature at which free energy change for reaction will be zero, is

Answer»

373 K
413 K
463 K
493 K

Solution :`DeltaG=DeltaH-TDeltaS`
`DeltaG=0` at EQUILIBRIUM
`THEREFORE DeltaH=TDeltaS` or `30.56=Txx0.066`
T=463 K.
