About phase rule

  1. Oct 20, 2015 #1
    1. The problem statement, all variables and given/known data
    Acording to the Gibbs phase rule, what is the maximum number of phases that one may observe for a binary mixture in equilibrium?

    2. Relevant equations
    phase rule
    F=C-P+2

    3. The attempt at a solution
    It says binary mixture but does it mean there are 2 component(C=2)?
    I think we can know one mole fraction and we can know another so C=1
    I found the answer for this problem is 4 from 0=2-P+2 P=4
    but if C=1 0=1-P+2 P=3

    Oh I lost some words
    I mean if one of the two mole fraction is known and the other is known so C=1
    what is the correct answer ? maximum number of phase is 3 or 4?

    Yes, that's what it means.
