The textbook definition of equilibrium is " a dynamic point reached by a reversible reaction in which the the rate of the forward reaction is equal to the rate of the reverse reaction. There is no net change in the concentration of the products and reactants over time."
If we take the following reversible reaction:
aA +bB ⇔ cC + dD
The equation for the equilibrium constant is
K = [C]c[D]d/[A]a[B]b
where a,b,c, and d are coefficients.
