A term that describes the state of a phase in which an energy barrier considerably higher than \(k\ T\) must be surmounted before this phase can transform to a phase of lower molar @G02629@ and molar @H02772@, where \(k\) is the @B00695@ and \(T\) the @T06321@.
In a thermodynamic sense, the equilibrium state is the state with the lowest molar Gibbs energy; a @M03872@ state corresponds to a relative minimum in the molar Gibbs energy.
