### What is Gibbs' Phase Rule? | Phase Rule Details

Gibbs phase rule equation is proposed by Josiah Willard Gibbs in the year 1875. This phase rule is based on the laws of thermodynamics and gives tge theoretical principle of characterizinf the system's chemical state. It predicts the equilibrium relations of phases and represent it as the function of physical condition like pressure and temperature.

The Gibbs phase rule equation is **F = C - P + factor**

Where,

F is the number of degrees of freedom

C is the number of components

P is the number of phases in the system

Factor depends on the temperature and pressure of the system

### Phase Rule Details

The phase rule equation contains number of phases, number of components, and number of degrees of freedom details.

**Number of Phases**

A phase is a form of matter that is homogenous in chemical composition and physical properties through its volume.

**Number of Components**

The minimum number of chemical components needed to constitute all phases in the system is the number of components.

**Number of Degrees of Freedom**

The number of degrees of freedom increases with the increase of number of components and decreases number of phases in balance.

**Example:**

**Question: Find the phase rule for the equation NH₄HCO₃(s) <-> NH₃(g) + CO₂(g) + H₂0(g).**

Answer:

Given that,

NH₄HCO₃(s) <-> NH₃(g) + CO₂(g) + H₂0(g)

Number of Components C = 2

Number of Phases P = 1

Factor = 2

Number of degrees of freedom F = C - P + factor

F = 2 + 1 - 2 = 1

Therefore, the number of degrees of freedom is 1.
