K p=K c ( R T ) ∆ n g
Kp = Kx . P Δng
Where,
∆ n g
= moles of gaseous products – moles of gaseous reactants.
Kc is the equilibrium constant expressed in terms of the concentration of the reactants/products. Similarly, Kp is the constant in terms of the partial pressures of the substances and K x is expressed in terms of the mole fraction.
Applications of the Law of Mass Action
This law is also applicable to semiconductors and, therefore, has several important implications in the fields of electronics and semiconductor physics. Here, the law of mass action provides a relationship between the concentrations of electron holes and free electrons when the semiconductor system is in a state of thermal equilibrium.
The law of mass action also has applications in the following fields:
- Mathematical ecology
- Sociophysics (social physics)
- Mathematical epidemiology
