Reactivity 2.3—How far? The extent of chemical change

Reactivity 2.3.1—A state of dynamic equilibrium is reached in a closed system when the rates of forward and backward reactions are equal.
Reactivity 2.3.2—The equilibrium law describes how the equilibrium constant, K, can be determined from the stoichiometry of a reaction.
Reactivity 2.3.3—The magnitude of the equilibrium constant indicates the extent of a reaction at equilibrium and is temperature dependent.
Reactivity 2.3.4—Le Châtelier’s principle enables the prediction of the qualitative effects of changes in concentration, temperature and pressure to a system at equilibrium.

Reactivity 2.3.5—The reaction quotient, Q, is calculated using the equilibrium expression with non- equilibrium concentrations of reactants and products.
Reactivity 2.3.6—The equilibrium law is the basis for quantifying the composition of an equilibrium mixture.
Reactivity 2.3.7—The equilibrium constant and Gibbs energy change, ΔG, can both be used to measure the position of an equilibrium reaction.
