There are three types of equilibrium constants, homogenous, heterogenous and multiple equilibrium constants. Homogenous equilibrium constant is the reactants and products being in a single solution. The states of reaction are all in the same phase (e.g. all aqueous solutions). Heterogenous equilibrium constant concentrates only on aqueous solutions and gas phases, the system has more than one phase. Multiple equilibrium constants involve 2 or more chemical reactions where we must add the equations together, the other processes remain the same as finding other equilibrium constants. Equilibrium constants are used to find Kc values to calculate and find out which way the chemical reaction will occur. If Kc > Qc the reaction will shift right.
