Good, I am new for the forum and it wanted to know if someone can help me with the following problem

For a regular solution in which the components have molecules of the same size, the free energy of mixture is:
ΔGM=RT (n₁LnX₁+n₂lnX₂)+(n₁+n₂) X₁X₂w

Where n denotes the quantity of components, X is the fraction to like and w is a parameter that measures the diversion of the law of raoult. Show that for such solutions, the chemical potentials are given for:

μ₁=μ₁°+RT lnX₁+wX²₂

μ₂=μ₂°+RT lnX₂+wX²₁

Since I can deduce an equation to estimate the coefficients of activity of the components in the dissolution
