Answer»

`dG = V dp - SdT` is applicaleforall process involvingboth 'PV'and non

Solution :(A)` G = H - TS = U + PV -TS`
`dG= dU +PdV +VdP -TdS-SdT`
`=q + W + PdV + VdP -TdS - SdT`
For a reversiblepath q= TdS
If there isno non-PVwork w = - PdV
`dG = VdP - SdT `(D) `G = H -TS + U+ PV -TS`
at constant 'T' & 'P'
`dG_("SYS") =dU + PdV -TdS_("sys")= q +w_(pv) +w_("non-PV") + PdV -TdS_("sys")`
SINCE`W_(PV) = - PdV`
andin theabsence of `w_(non-PV)`
`dG_("sys") = q -TdS_("sys")`
` dG_("sys") = - T(dS_("sys") + dS_("surr"))`
