The incorrect expression among the following is

Options

A. `(DeltaG_("system"))/(DeltaS_("Total")) =-T`
B. In isothermal process, `W_("reversible") = -nRT` ln `(V_(t))/(V_(i))`
C. `ln K=(DeltaH^(@) - TDeltaS^(@))/(RT)`
D. `K = e^(-DeltaG^(@)//RT)`

Answer

C

Explanation

`DeltaG = DeltaG^(@) + RT lnq`
At equilibrium `DeltaG=0` and `DeltaG^(@) =DeltaH-TDeltaS^(@)` and Q=R
`ln K =-(DeltaH^(@) - T DeltaS^(@))/(RT)`
