Le Chatelier's Principle
If a system at equilibrium is disturbed, it shifts to counteract the change: Adding reactant → shifts right. Adding product → shifts left. Exothermic: raising T shifts LEFT. Increasing pressure favors fewer gas molecules.
Chemical Equilibrium – Le Chatelier's Principle Online
Chemical equilibrium describes the dynamic state where forward and reverse reaction rates become equal, producing constant concentrations of reactants and products. This simulation lets you set initial concentrations, run a reversible reaction to equilibrium, then perturb the system by changing concentration, pressure, or temperature.
What you can do in this simulation
- Set initial concentrations of reactants and products and observe the system reach equilibrium
- Calculate and display the reaction quotient Q and equilibrium constant K in real time
- Apply Le Chatelier's principle by adding reactant, removing product, or changing pressure
- Shift temperature for exothermic vs. endothermic reactions and observe K changing
- Visualize concentration-vs-time graphs as the system finds a new equilibrium
Concepts covered
equilibrium constant Kc · reaction quotient Q · Le Chatelier's principle · reversible reactions · dynamic equilibrium
