" /> chemical potential - CISMeF





Preferred Label : chemical potential;

Detailed label : chemical potential, μB;

IUPAC definition : The chemical potential of a substance strong B /strong in a mixture of substances strong B /strong , strong C /strong ... is related to the Gibbs energy G of the mixture by: \[μ _{{B}} (\frac{ G}{ n_{{B}}})_{T,p,n_{{C}\neq {B}}}\] where T is the thermodynamic temperature, p is the pressure and n B, n C, ... are the amounts of substance of strong B /strong , strong C /strong , ... . For a pure substance strong B /strong , the chemical potential µ B * is given by: \[μ _{{B}} {*} \frac{G {*}}{n_{{B}}} G_{{m}} {*}\] where Gm* is the molar Gibbs energy, and where the superscript * attached to a symbol denotes the property of the pure substance. The superscript Θ or attached to a symbol may be used to denote a standard thermodynamic quantity.;
