Mixture adsorption equilibria predicted from two pure-component isotherms
(Myers & Prausnitz 1965): equal spreading pressures ψ
1(p₁⁰) = ψ
2(p₂⁰)
with Py
i = x
ip
i0. Spreading pressures are analytic for most models;
the solver bisects a strictly monotone function of x
1, so the solution is unique and always found.
