Law of Chemical Equilibrium and Its Thermodynamic Derivation

The law of chemical equilibrium is a fundamental concept in chemistry that describes the state of a chemical reaction when the rate of the forward reaction is equal to the rate of the reverse reaction. This dynamic equilibrium is governed by the principle of mass action and is influenced by factors such as temperature, pressure, and concentration of reactants and products.

Thermodynamically, the law of chemical equilibrium can be derived from the principles of thermodynamics, particularly the concept of free energy and entropy. Relationship between equilibrium constant and free energy change can expressed using equation ΔG = -RTlnK, where ΔG is change in free energy, R is gas constant, T is temperature in Kelvin, and K is equilibrium constant. This equation provides a thermodynamic basis for understanding the behavior of chemical systems at equilibrium.

Derivation of the Law of Chemical Equilibrium

To understand thermodynamic derivation Derivation of the Law of Chemical Equilibrium, let`s consider following scenario as an example:

ReactantsProducts
2A + 3BC + D

In this hypothetical reaction, the equilibrium constant, K, is determined by the ratio of the concentrations of the products to the concentrations of the reactants at equilibrium. Expression for K is given by:

K = [C]^c[D]^d / [A]^a[B]^b

Where [C], [D], [A], and [B] represent the molar concentrations of the respective species, and c, d, a, and b represent the coefficients of the balanced chemical equation.

By applying the principles of thermodynamics, we can relate the equilibrium constant to the change in free energy through the equation:

ΔG = ΔG° + RTlnQ

Where ΔG° is standard free energy change, R is gas constant, T is temperature in Kelvin, and Q is reaction quotient. At equilibrium, the reaction quotient is equal to the equilibrium constant, K.

Through this thermodynamic derivation, we can gain insights into the factors that influence the position of equilibrium and the extent of a chemical reaction. Moreover, it provides a framework for predicting the behavior of chemical systems under different conditions.
