Basic Definitions

At constant temperature and pressure, the chemical potential of a solute component k in a solution can be written as
$$ {\upmu_{{k}}} = {\upmu_{{k}}}^{\infty } + {\mathrm{ R}{T}\mathrm{ ln}}\ {{\mathrm{ a}}_{{k}}} = {\upmu_{{k}}}^{{\infty (\mathrm{ m})}} + {\mathrm{ R}{T}\mathrm{ ln}}\ {{\mathrm{ m}}_{{k}}}{\upgamma_{{k}}} $$
