## Homework Statement

"By applying Gibbs' phase rule to show that for an n component system, no more than n+2 phases may coexist at equilibrium

## Homework Equations

P+F=C+2

## The Attempt at a Solution

Because the question says that P = n +2 I subbed this in => n+F=C. I'd like to sub some numbers in to prove that you can't have more than n +2 phases, but with regards to the other numbers surely you can have a very large number of degrees of freedom and many components.

So what do I do? I really don't understand how I can prove this sensibly
