Equilibrium Constant (K):K represents the ratio of product concentrations to reactant concentrations at equilibrium. It helps us understand how far a reaction will proceed in terms of products versus reactants.
Le Chatelier's Principle: This principle states that when a system at equilibrium is disturbed, it will adjust itself in order to counteract the disturbance and restore equilibrium. It helps us predict how changes in conditions such as temperature or pressure affect an equilibrium system.
Reaction Quotient (Qc): Similar to Q, Qc calculates the ratio of product concentrations to reactant concentrations for any point during a reaction, not just at equilibrium. By comparing Qc to K, we can determine whether a system has reached equilibrium yet or if it needs more time to shift towards balance.
