How do we derive the equilibrium constant formula?
ie: Kc= [C]^c*[D]^d/ [A]^a*^b
Thanks in advance.

The equilibrium constant formula is a mathematical equation that expresses the ratio of the concentrations of products to reactants at equilibrium for a given chemical reaction. It is represented by the symbol Kc or Kp, depending on whether concentrations or pressures are used.
The equilibrium constant formula is derived from the law of mass action, which states that the rate of a chemical reaction is proportional to the product of the concentrations of the reactants. By setting the rates of the forward and reverse reactions equal to each other at equilibrium, we can solve for the equilibrium constant.
The value of the equilibrium constant is affected by factors such as temperature, pressure, and the initial concentrations of reactants and products. It is also influenced by the stoichiometry of the reaction, as well as any changes in concentration or pressure that occur during the reaction.
No, the equilibrium constant formula can only be applied to reversible reactions, where both the forward and reverse reactions are occurring. It also assumes that the reaction is taking place in a closed system, where no reactants or products are added or removed.
If the value of the equilibrium constant is greater than 1, it indicates that the products are favored at equilibrium, and the reaction will proceed towards the right. If the value is less than 1, it means the reactants are favored, and the reaction will proceed towards the left. If the value is equal to 1, the reaction is at equilibrium and there will be no net change in the concentrations of reactants and products.
