Question

Given the adjacent phase diagram, apply the Gibbs phase rule to calculate the degrees of freedom. State the number of species, phases, and show your calculations in every case for full credit. F = 2 -;pi + N where pi is the number of phases present, N is the number of chemical species present, and F is the number of degrees of freedom that the system has. for point O (the triple point) any point on the line Oc (other than O) any point inside the liquid (water) phase the normal boiling point of water

Explanation / Answer

Answer:-

i). For point O (triple point), Triple point is the where all the phases of water in equilibrium,

So, degree of freedom,

F= 2-3+1

F= 0

ii).Any point on the Oc line(other than O)

Oc line is the equilibrium between liquid and vapour phase,

So, F=2-2+1

F=1

iii).Any point inside the liquid phase,

In the liquid phase, F= 2-1+1

F= 2

iv). The normal boiling point of water = 100oC

because the boiling point at the 1 atm pressure is known as normal boiling point.
