Equilibrium Constant Calculator with Temperature...
Calculate equilibrium constants Kc and Kp for chemical reactions and understand how temperature shifts equilibrium using the Van't Hoff equation. Includes Le Chatelier's Principle.
What is the Equilibrium Constant?
The equilibrium constant (K) quantifies the ratio of product to reactant concentrations at chemical equilibrium. A large K means products are favored; a small K means reactants dominate. K depends only on temperature, not on initial concentrations or pressure.

📐 Formula
Kc = [products]^n / [reactants]^m
Concentrations in mol/L, raised to stoichiometric powers. Kp uses partial pressures. Relationship: Kp = Kc × (RT)^Δn.
📝 Worked Example
N₂ + 3H₂ ⇌ 2NH₃
Kc = [NH₃]² / ([N₂][H₂]³)
At 500°C, Kc ≈ 6×10⁻². Products not favored at high T (Haber Process uses high P to compensate).

❓ FAQ
What does Q vs K tell us?
If Q < K: reaction proceeds forward. If Q > K: reaction proceeds backward. If Q = K: system is at equilibrium.
What is Le Chatelier's Principle?
If a system at equilibrium is disturbed (change in concentration, pressure, or temperature), it will shift to minimize the disturbance and re-establish equilibrium.
