WebDec 31, 2016 · The Gibbs' Phase rule is:. #f = 2 + c_i - p# #c_i = c - r - a#. where: #f# is the number of degrees of freedom (how many independent intensive variables can be varied without affecting other thermodynamic variables).; #c_i# is the number of chemically independent components in the system. #c# is the number of components in the … WebGibbs phase rule expresses the degrees of freedom, F, of a multiphase system in terms of the number of phases, P, present, the number of components, C, and two thermodynamic parameters, normally (p, T). This has the form: F = C - P + 2. In many cases, the pressure is a constant and the Gibbs phase rule for a constant pressure system is: F p = C ...
