Chapter 4, Problem 4.4DQ

Interpretation Introduction

Interpretation:

A detailed explanation of phase diagram of Sulphur by using phase rule has to be done.

Concept Introduction:

Phase rule:

The phase rule can be mathematically represented as:

  $F=C-P+2$

Where,

• F is the number of degrees of freedom of a system, the number of intensive variables that can be changed independently without disturbing the number of phases in equilibrium.
• C, the number of components, is the minimum number of independent species necessary to define the composition of all the phases present in the system.
• P is the number of phases present in equilibrium.
