4.62. Like the entropy of mixing, a Gibbs energy of mixing for gases can be derived: no of gases Amix G = RT Σ n₁ Inx; i=1 where n, is the number of moles and x; is the mole fraction of the ith gas. (a) Derive this equation. Hint: assume AmixH = 0 and use equation 3.25. (b) Show that mixing is always spon- taneous by demonstrating that AmixG is always less than zero for a mixture of gases. (c) Calculate AmixG when 1.0 mol Ne, 2.0 mol He, and 3.0 mol Ar are mixed at 35.0°C.
