Question:

The incorrect expression among the following is:
In isothermal process, Wreversible = −nRTln(Vf/Vi)
K = e^−ΔGo/RT
lnK = ΔH⁰ − TΔS⁰/RT
ΔGsystem = ΔStotal = −T

ΔGsystem = ΔStotal = −T

lnK = ΔH⁰ − TΔS⁰/RT

K = e^−ΔGo/RT

In isothermal process, Wreversible = −nRTln(Vf/Vi)

Solution:

ΔGo = −RTlnK (i)
ΔGo = ΔHo − TΔSo. (ii)
From (i) and (ii), −(ΔHo + TΔSo) = RT lnK
Hence, option (C) is incorrect answer.
