Chemical Equilibrium Lab

Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped, but in fact, the rates of the forward and reverse reactions are equal, causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD Equation 1
Equation 2 below will give the equilibrium constant, Keq, for this general reaction, where the square brackets refer to the molar concentration of the reactants and products at equilibrium.
K_eq= (〖[C]〗^c [D]^d)/([A]^a [B]^b )
