Question

State the Law of mass Action? Derive the law of chemical Equilibrium and hence define Equilibrium constent?
​

Answer 1

Answer:

The law of mass action states that the rate of a reaction is proportional to the product of the concentrations of each reactant. ... The law of mass action also suggests that the ratio of the reactant concentration and the product concentration is constant at a state of chemical equilibrium.

Answer 2

Answer:

In chemistry, the law of mass action is the proposition that the rate of the chemical reaction is directly proportional to the product of the activities or concentrations of the reactants. It explains and predicts behaviors of solutions in dynamic equilibrium

For any reversible reaction, The law of mass action is applied to derive a mathematical expression for equilibrium constant. This is known as law of chemical equilibrium. ... The combined constant, K which is equal to kf / kb is called equilibrium constant and has value for a reaction at a given temperature.
