Number of degrees of freedom for a three phase system in equilibrium comprising of three non-reacting chemical species is__________________?
Correct answer: A. 2
- A. 2
- B. 0
- C. 1
- D. 3
Explanation
Gibbs phase rule gives F = C - P + 2 = 3 - 3 + 2 = 2. Therefore, two intensive variables can be independently specified while maintaining three-phase equilibrium.
