The Law of Chemical Equilibrium The equilibrium constant is not dependent on initial concentrations but varies with temperature. Thus, this constant describes the endpoint of a reversible reaction; we can use it to determine which reaction, either the forward or the reverse reaction, is favoured if we know the concentrations at any time within a chemical system. For a general chemical equation: The general expression for the constant is: K eq = The constant K is called the equilibrium constant. The following is a list of conditions which must be satisfied when working with the equilibrium constant. a. K can be an extremely large number, or even a very small number, but K can never be zero or negative. So, K>0. b. The numerical value of K can only be known through experiments. c. Each substance must be present at equilibrium. If this condition were not satisfied, one of the concentration terms would equal zero. d.
