WebApr 12, 2024 · A binary two-phase system has two degrees of freedom. At a given T and p, each phase must have a fixed composition. We can calculate the liquid composition by rearranging Eq. 13.2.4: xA = p − p ∗ B p ∗ A − p ∗ B The gas composition is then given by yA = pA p = xAp ∗ A p = ( p − p ∗ B p ∗ A − p ∗ B)p ∗ A p.
