Excess Gibbs energy of an ideal dilute solution

Excess Gibbs energy of an ideal dilute solution 

According to expression [A.2.31] (see Table A.2.2 in Appendix 2), we immediately obtain  

This excess Gibbs energy is non-null, but in that excess Gibbs energy, there is no contribution fi-om the solvent () = 1). 

We can see that because the exeess Gibbs energy is not null, we have another reason to avoid eonfusing an ideal dilute solution with a perfect
