Flory–Huggins solution theory

<p>Flory–Huggins solution theory is a <a href="/facts/Lattice_model_(physics)/TY3bVAhk">lattice model</a> of the <a href="/facts/Thermodynamics/q4hIx3yP">thermodynamics</a> of <a href="/facts/Polymer_solution/RPssrPMD">polymer solutions</a> which takes account of the great dissimilarity in <a href="/facts/Molecule/N9ljSfFq">molecular</a> sizes in adapting the usual <a href="/facts/Expression_(mathematics)/MPrMlYbE">expression</a> for the <a href="/facts/Entropy_of_mixing/zDdJNHTe">entropy of mixing</a>. The result is an equation for the <a href="/facts/Gibbs_free_energy/bvenDuzh">Gibbs free energy</a> change
