Question

In a three-component system of phase equilibria, the maximum number of degrees of freedom can be: (use the phase rule \(F = C - P + 2\), with the minimum number of phases \(P = 1\))

• A. 4
• B. 3
• C. 2
• D. 1

Hint:

Degrees of freedom are maximum when the number of phases is minimum, P=1.

Answer 1

The Correct Option is A

Single phase (P=1) imposes no coexistence constraints, allowing max flexibility. F=3-1+2=4.

\[\boxed{F_{max} = 4}\]
