Equilibrium Constant - Chemistry Steps

Like any other conjugate acid–base pair, the strengths of the conjugate acids and bases are related by pKa + pKb = pKw. P is pressure, V is volume, n is the number of moles, and T is temperature. The magnitude of the equilibrium constant, K, indicates the extent to which a reaction will proceed: If K is a large number, it means that the equilibrium concentration of the products is large.
