The maximum number of degrees of freedom (F) for a system of C-components is by: a) C-1 b) C+1 c) C-2 d) C+2

The Gibbs Phase Rule: P + F = C + 2

 

 the maximum number of possible assemblages with C phases (assemblages with a stability field, F=2) 

 

 The maximum number of possible assemblages with C+1 phases (assemblages defining a reaction, F=1) 
- The maximum number of possible assemblages with C+2 phases (The maximum number of phases that can coexist, F=0)
