GIBB’S PHASE RULE F = C–P+2 THERMODYNAMIC DERIVATION 3 STEPS TO DERIVE PHASE RULE

GIBB’S PHASE RULE F = C–P+2 THERMODYNAMIC DERIVATION 3 STEPS TO DERIVE PHASE RULE 1.To find the total number of variables (or) deg of freedom. 2. To find the total thermodynamic constraints (or) restrictions. 3. The number of deg of freedom = 1 – 2 DEGREES OF FREEDOM F = C – P + 2 THIS EQUATION IS CALLED GIBB’S PHASE RULE
