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 @[email protected] and molar @[email protected], where \(k\) is the @[email protected] and \(T\) the @[email protected]
In a thermodynamic sense, the equilibrium state is the state with the lowest molar Gibbs energy; a @[email protected] state corresponds to a relative minimum in the molar Gibbs energy.
