Chemical Equilibrium & Le Chatelier’s Principle

Added: 2026-05-28

[00:00:00]Imagine a chemical reaction in a closed system where reactants turn into products and vice versa. When the rates of the forward and reverse reactions become equal, the system reaches chemical equilibrium, [music] no net change in concentrations.

[00:00:14]Le Chatelier's principle predicts how equilibrium shifts. [music] Increasing reactant concentration, pressure, or decreasing temperature for exothermic reactions [music] pushes the system to favor products.

[00:00:26]Conversely, increasing product concentration, decreasing pressure, or raising temperature favors reactants.

[00:00:33]The system always shifts to minimize the disturbance.
