Equilibrium Constant Formula

A number which shows the relationship between the amounts of reactants and products present at equilibrium in a chemical reaction which is reversible at a given temperature is termed as equilibrium constant. Here is the Equilibrium constant formula for calculating equilibrium constant Kp using partial pressures for the given chemical equation. This Dalton's law partial pressure formula will be the useful formula for you to simplify and balance your chemical equations.

Partial Pressure Formula

Formula:

Given Equation aA + bB = cC + dD
Kp = (PC)c (PD)d / (PA)a (PB)b


Where,

Kp = Equilibrium Constant
PA = Partial Pressure of Product A
PB = Partial Pressure of Product B
PC = Partial Pressure of Reactant C
PD = Partial Pressure of Reactant D
