How chemical systems fight back against external changes
In short: Discover the logic of Le Chatelier's Principle. This video explains how reversible reactions automatically adjust their internal balance to counteract shifts in temperature, pressure, and concentration.
Le Chatelier's Principle describes the behavior of systems at equilibrium. When a change is imposed on a reversible reaction, the system shifts its position to oppose that change. This is a fundamental concept in chemistry for understanding how substances behave under different environmental conditions.
The video covers three primary drivers of equilibrium shifts: temperature, pressure, and concentration. It distinguishes between exothermic and endothermic reactions to show how heat affects the balance. It also explains how pressure changes impact systems with different numbers of gas moles, and how altering the concentration of reactants or products forces the reaction to compensate.
