About Chemical Equilibrium

Chemical equilibrium occurs when the rates of forward and reverse reactions are equal, resulting in no net change in concentrations.

Key Concepts:

Kc: Concentration-based equilibrium constant
Kp: Pressure-based equilibrium constant
Reaction Quotient (Q): Current ratio of products to reactants
Le Chatelier's Principle: System responds to changes to restore equilibrium

Applications:

Industrial chemical synthesis
Environmental chemistry
Biochemical processes
Catalysis research
Chemical engineering
Analytical chemistry
