    14.1 : Dynamic Equilibrium02:20

    14.1 : Dynamic Equilibrium

    A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When ...

    14.4 : Calculating the Equilibrium Constant

    The equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these ...

    14.5 : Reaction Quotient02:35

    14.5 : Reaction Quotient

    The status of a reversible reaction is conveniently assessed by evaluating its reaction quotient (Q). For a reversible reaction described by m A + n B ...

    14.7 : Le Chatelier's Principle: Changing Concentration02:27

    14.7 : Le Chatelier's Principle: Changing Concentration

    A system at equilibrium is in a state of dynamic balance, with forward and reverse reactions taking place at equal rates. If an equilibrium system is ...

    14.8 : Le Chatelier's Principle: Changing Volume (Pressure)02:32

    14.8 : Le Chatelier's Principle: Changing Volume (Pressure)

    For gas-phase equilibria, changes in the concentrations of reactants and products can occur with altered volume and pressure. The partial pressure, P, of ...

    14.9 : Le Chatelier's Principle: Changing Temperature02:19

    14.9 : Le Chatelier's Principle: Changing Temperature

    Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in ...

    14.10 : The Small x Assumption02:20

    14.10 : The Small x Assumption

    If a reaction has a small equilibrium constant, the equilibrium position favors the reactants. In such reactions, a negligible change in concentration may ...
