Chemical Equilibrium Simulator Temperature

For an exothermic forward reaction, raising temperature lowers the product-favored tendency; cooling favors products.

Open Chemical Equilibrium Simulator

Chemical Equilibrium Simulator Pressure

Higher pressure favors the side with fewer gas moles, so this reaction tends to shift toward products when compressed.

Chemical Equilibrium Simulator FAQ

Fast answers about Chemical Equilibrium Simulator reactions, equilibrium constants, Le Chatelier principle, pressure, temperature, and catalysts.

Is Chemical Equilibrium Simulator free?

Chemical Equilibrium Simulator is free and runs in the browser without an account.

Which reactions does Chemical Equilibrium Simulator support?

Start Chemical Equilibrium Simulator here: choose a reaction such as N2 + 3H2 ⇌ 2NH3, set concentrations, temperature, pressure, and catalyst, then read the shift direction and explanation.

How does Chemical Equilibrium Simulator decide left or right shift?

Chemical Equilibrium Simulator compares the reaction quotient Q with the equilibrium constant K. If Q is less than K, the model shifts right; if Q is greater than K, it shifts left; if Q is close to K, the curves stay near equilibrium.

Does Chemical Equilibrium Simulator show the equilibrium constant?

Yes. Chemical Equilibrium Simulator shows both the equilibrium constant K and the reaction quotient Q beside the concentration curves.

Does a catalyst change the equilibrium position in Chemical Equilibrium Simulator?

Speeds up the approach to equilibrium without changing K or final concentrations.

Start Chemical Equilibrium Simulator now

Open Chemical Equilibrium Simulator, choose a reversible reaction, and watch reactants and products approach equilibrium.

Then change concentration, temperature, pressure, or catalyst and read why the balance shifts left, shifts right, or stays near equilibrium.
