equilibrium expression

Front

the expression obtained by multiplying the product concentrations and dividing by the multiplied reactant concentration, with each concentration raised to a power represented by the coefficient in the balanced equation

Back

equilibrium position

Front

a particular set of equilibrium concentrations

Back

equilibrium constant

Front

the value obtained when equilibrium concentrations of the chemical species are substituted in the equilibrium expression

Back

chemical equilibrium

Front

a dynamic reaction system in which the concentrations of all reactants and products remain constant as a function of time

Back

law of mass action

Front

a general description of the equilibrium condition; it defines the equilibrium constant expresssion

Back

homogeneous equilibrium

Front

an equilibrium system where all reactants and products are in the same phase

Back

Le Chatelier's principle

Front

if a change is imposed on a system at equilibrium, the position of the equilibrium will shift in a direction that tends to reduce the effect of that change

Back

reaction quotient Q

Front

a quotient obtained by applying the law of mass action to initial concentrations rather than to equilibrium concentrations

Back

heterogeneous equilibrium

Front

an equilibrium involving reactants and/or products in more than one phase
