Chemical reaction: 4PBr₃ (g) → P₄ (g) + 6Br₂ (g).

Pressure equilibrium constant (Kp) express the relationship between product pressures and reactant pressures. The partial pressures of gases are used to calculate pressure equilibrium constant.

Kp = (p (P₄) · p (Br₂) ⁶) : p (PBr₃) ⁴.

p (P₄) - partial pressure of phosphorus.

p (Br₂) - partial pressure of bromine.
