Explain the equation of the law of equilibrium

aA(g)+bB(g)⇌cC(g)+dD(g) then the equilibrium constant defined by the equation. Kc=[ C ]c[ D ]d[ A ]a[ B ]b. is found to be a constant quantity depending only on the temperature and the nature of the reaction. This general result is called the law of chemical equilibrium, or the law of mass action.

Explanation: Since kf and kr are constants, the ratio of kf divided by kr must also be a constant. This ratio is the equilibrium constant for the reaction, Kc. The ratio of the concentrations of the reactants and products is known as the equilibrium constant expression.
