equilibrium
|
state of a reversible reaction in which the forward and reverse processes occur at equal rates
|
|
|
|
|
|
equilibrium constant (
K
)
|
value of the reaction quotient for a system at equilibrium; may be expressed using concentrations (
K
c
) or partial pressures (
K
p
)
|
|
|
|
|
|
heterogeneous equilibria
|
equilibria in which reactants and products occupy two or more different phases
|
|
|
|
|
|
homogeneous equilibria
|
equilibria in which all reactants and products occupy the same phase
|
|
|
|
|
|
law of mass action
|
when a reversible reaction has attained equilibrium at a given temperature, the reaction quotient remains constant
|
|
|
|
|
|
Le Chatelier’s principle
|
an equilibrium subjected to stress will shift in a way to counter the stress and re-establish equilibrium
|
|
|
|
|
|
reaction quotient (
Q
)
|
mathematical function describing the relative amounts of reactants and products in a reaction mixture; may be expressed in terms of concentrations (
Q
c
) or pressures (
Q
p
)
|
|
|
|
|
|
reversible reaction
|
chemical reaction that can proceed in both the forward and reverse directions under given conditions
