Gibbs Phase rule defines the
relationship between degrees of freedom (F)
of a system, number of phases (P) and
the number of components (C). What is
the equation?
गिब्स चरण नियम एक प्रणाली की स्वतंत्रता की डिग्री (F ), फेज की संख्या (P ) और घटकों की संख्या (C ) के बीच संबंध को परिभाषित करता है। समीकरण क्या है?
F - P = C
F - P = C
F + P = C + 2
F + P = C - 2
F + P = C + 2
According to Gibbs phase rule
F = C
– P + 2
Where,
F = Degree of freedom (DOF)
C = Number of components
P = Number of phase
Hence, the correct option is (C).
&Key Points:-
Gibbs phase
rule can only be applied for pure substances and is invalid at critical point.
