Question

How to calculate degree of freedom for azeotropic mixture?

Answer 1

Answer:

What are the degrees of freedom (from Gibbs phase rule) for an azeotropic mixture? For an azeotropic binary mixture, the number of phases is 2 and number of components are 2. So, according to Gibbs phase rule, the number of degrees of freedom should be 2. But, the right answer is 1.
