The phase rule is a generalization given by Willard Gibbs (1874), which seeks to explain the equilibria existing in heterogeneous system. It may be stated as: вЂњprovided the equilibrium between any number of phases is not influenced by Phase rule definition is - a law in physical chemistry: the number of degrees of freedom of a system in equilibrium is equal to the number of components minus the number of phases plus the constant two (as in the system ice -liquid water- water vapor consisting of the one chemical component water and its three physical phases there are no degrees of freedom and the system can exist at only one

Gibbs' Phase Rule. The Phase Rule describes the possible number of degrees of freedom in a (closed) system at equilibrium, in terms of the number of separate phases and the number of chemical constituents in the system. It was deduced from thermodynamic principles by J. W. Gibbs in the 1870s. Chapter 7 What Controls the Composition of Riverwater and Seawater: Equilibrium versus Kinetic Ocean (4/15/01) James W. Murray The first approaches to this problem were attempts to explain the composition of seawater in terms The framework for constructing such multicomponent equilibrium models is the Gibbs Phase Rule. This rule is

3. Explain condensed / reduced phase rule. 4. (a) вЂњThe eutectic is a mixture not a compoundвЂќ. Justify. (b) State phase rule and explain the terms involved in it. 5. With the help of a neat phase diagram, describe lead вЂ“ silver system (OR) Discuss phase rule and its applications to desilverization of lead. 6. Broadly two kinds of phase diagrams can be differentiated* в†’ those involving time and those which do not involve time (special care must be taken in understanding the former class- those involving time). In this chapter we shall deal with the phase diagrams not involving time.

The phase rule is a generalization given by Williard Gibbs (1876) which seeks to explain the equilibria existing in heterogeneous systems. With the application of phase rule it is possible to predict qualitatively by means of a diagram the effect of changing pressure, temperature and concentration on a heterogeneous system in equilibrium. The the interpretation and calculation of phase diagrams of all types. In Sec. 3 the Gibbs Phase Rule is developed in a general form suitable for the understanding of phase diagrams involving a wide range of variables including chemical potentials, enthalpy, volume, etc. Sec. 4 begins with a review of the thermodynamics of solutions and
