  • Equilibrium State
    A condition where reactant and product concentrations remain constant over time in a reversible reaction.
  • Reversible Reaction
    A chemical process where reactants form products and products can revert to reactants.
  • Equilibrium Constant
    A value representing the ratio of product to reactant concentrations at equilibrium, affected by temperature.
  • Forward Direction
    The path in a reaction where reactants are converted into products.
  • Reverse Direction
    The path in a reaction where products revert back to reactants.
  • Kc
    An equilibrium constant for reactions in aqueous solutions, using molarity as the unit.
  • Kp
    An equilibrium constant for gaseous reactions, using partial pressure in atmospheres.
  • Delta n
    The difference in moles of gaseous products and reactants, used in the Kp and Kc relationship.
  • Gas Constant
    A constant used in calculations involving gases, typically 0.08206 L·atm/mol·K for equilibrium.
  • Acid Dissociation Constant
    Represented as Ka, it measures the strength of an acid in solution.
  • Base Dissociation Constant
    Represented as Kb, it measures the strength of a base in solution.
  • Partial Pressure
    The pressure exerted by a single gas in a mixture of gases.
  • Molarity
    A concentration unit defined as moles of solute per liter of solution.
  • Temperature
    A factor that affects the equilibrium constant, influencing the direction of a reaction.
  • Plateau
    A stage in a reaction where concentrations of reactants and products remain unchanged.
