Regular Solution

In the regular solution, the enthalpy of mixing ΔH is dependent on mole fractions of the components of the binary mixture:
The entropy of mixing ΔS is the ideal entropy of mixing.
The Gibbs energy of mixing is:
The plot shows the enthalpy, the entropy and the Gibbs energy of the regular solution.
