Equilibrium Law - Kc
For any general reaction shown below:
The equilibrium constant (Kc) is as follows:
Kc is a constant at constant temperature ( for more on how Kc changes with temperature, you will need to look into Gibbs free energy, which I have not covered on this site thus far.) Kc controls the amounts of reactants and products in the equilibrium. If the concentration of something is changed then the proportions of reactants and products change so as to keep the Kc constant. If more reactants are added, then the amount of products must increase so as to maintain a constant Kc.
