equilibrium constant expression


equilibrium constant expression
The ratio of the concentrations of products in a balanced chemical equationA representation of a chemical reaction in which chemical symbols represent reactants on the left side and products on the right side., each concentration raised to the power of its coefficient, divided by the concentrations of reactants, each raised to the power of its coefficient; at equilibriumA state in which no net change is occurring, that is, in which the concentrations of reactants and products remain constant; chemical equilibrium is characterized by forward and reverse reactions occurring at the same rate. this ratio has the value of the equilibrium constantThe value of the equilibrium constant expression when equilibrium concentrations are substituted; a value greater than one indicates the position of equilibrium lies toward products (product-favored), and a value less than one indicates the position of equilibrium lies toward reactants (reactant-favored)..
