For a thermodynamic system containing 'x' chemical species, the maximum number of phases that can co-exist at equilibrium is_________________?
Correct answer: C. x + 2
- A. x
- B. x + 1
- C. x + 2
- D. x + 3
Explanation
The Gibbs phase rule is F = x - P + 2. Setting the degrees of freedom F to zero gives the maximum equilibrium phases as P = x + 2.
