Question

Determine the number of phases, components and degrees of freedom in the following equilibria : (0) CaCO3=Cao(s) +CO2g)

​

Answer 1

Answer:

The Phase Rule for non reacting systems is given by:

F = 2 - P + N

F = Number of degrees of freedom

P = Number of distinct phases present during equilibrium

N = Number of chemical species present during equilibrium.

Answer 2

Answer:

No. of phase (P) = 1

No. of components (C)= 3

Freedom (F)= C-P+2

= 3-1+2

= 4
