The Chemical Equilibrium Constant Calculator helps you quickly calculate the equilibrium constant (Kc or Kp) of a chemical reaction. This is a very useful tool for chemistry students and anyone studying reaction dynamics.
What is a Chemical Equilibrium Constant?
The equilibrium constant tells us how far a chemical reaction proceeds before reaching a balanced state. There are two common types of equilibrium constants:
- Kc – Based on concentration (mol/L)
- Kp – Based on partial pressures (atm)
Formula for Kc and Kp
The general formula for Kc is:
Kc = [products]^n / [reactants]^m
For gases, the Kp formula is:
Kp = (P_products)^n / (P_reactants)^m
For the reaction: H₂ + I₂ ⇌ 2HI
If [H₂] = 0.5 mol/L, [I₂] = 0.5 mol/L, and [HI] = 1 mol/L:
Kc = [HI]² / ([H₂][I₂]) = (1)² / (0.5 × 0.5) = 4
