Term
Reversible Reaction
Definition
a chemical reaction in which the products can react to reform the reactants
Term
Chemical Equilibrium
Definition
a reversible chemical reaction is when the rate of its forward reaction equals the rate of its reverse reaction and the concentrations of its products and reactants remain unchanged
Term
Equilibrium Constant
Definition
is the ratio of the mathematical product of the concentrations of substances formed at equilibrium to the mathematical product of the concentrations of reacting substances.
Term
Chemical Equilibrium Expression
Definition
Each concentration is raised to a power euqal to the coefficient of that substance in the chemical equation the Chemical K is sometimes reffered to as this.
Term
