State chemical equilibrium precisely and explain why it matters in 2-3 sentences.

# Chemical Equilibrium **Precise statement:** A chemical equilibrium exists when the forward and reverse reaction rates are equal, resulting in no net change in the concentrations of reactants and products over time (though both reactions continue occurring at the molecular level). **Why it matters:** Equilibrium determines the maximum yield obtainable in reversible reactions, which is critical for optimizing industrial processes like ammonia synthesis and predicting the extent of reactions in biological systems. Understanding equilibrium allows chemists to manipulate conditions (temperature, pressure, concentration) to shift product formation in desired directions via Le Chatelier's principle.
