Which of the following Maxwell relation is INCORRECT?

Explanation:

If there is a relation between x, y & z, then z may be expressed as a function of x & y.

An equation of type dz = Mdx + Ndy  is exact differentials, it can be written as 

For a pure substance undergoing a reversible process, these equations hold true:

1. dU = T.ds – p.dv
2. dH = T.ds + v.dp
3. dF = -p.dV – s.dT
4. dG = v.dP –s.dT

They can be written as

These are known as Maxwell’s Equation.

Out of these options, 4 does not match with Maxwell’s Equation.

Other Maxwell relations are:

if x =  ϕ(y, z)

If F = ϕ(x, y, z)
