3. Gibbs phase rule and lever arm rule

In this section, we group together two rules of unequal importance. Gibbs' phase rule is universal in scope, and enables us to count the coexisting phases in a system of any multiplicity, in relation to the number of degrees of freedom in that system. The second rule, known as the lever arm or inverse segment rule, applies only to binary systems, and is a geometric image of the mass balance of the two phases in a two-phase domain.
