Equilibrium:In reversible reactions, equilibrium refers to when both forward and reverse reactions occur at equal rates, resulting in no net changes in concentrations.
Activation Energy:Activation energy is the minimum amount of energy required for reactant molecules to undergo a successful collision and initiate a chemical reaction.
Le Chatelier's Principle: This principle states that if an external stress or change is applied to a system at equilibrium, it will respond by shifting towards minimizing that stress or change.
