Le-Chatelier’s Principle

Science > Chemistry > Chemical Equilibrium > Le-Chatelier’s Principle In this article, we shall study Le-Chatelier’s principle with examples. Statement: This principle is given by, a French chemist Le-Chatelier in 1888. It states that “If an external stress is applied to a reacting system at equilibrium, the system will adjust itself in such a way […]

Equilibrium Constant

Science > Chemistry > Chemical Equilibrium > Equilibrium Constant Characteristics of Equilibrium Constant: It has a definite value for every chemical reaction at a particular temperature. It is independent of the initial concentrations of the reacting species. It changes with the change in the temperature. It depends on the nature of the reaction. It is […]

No Comments on Gibb’s Energy and Chemical Equilibrium

Science > Chemistry > Chemical Equilibrium > Gibb’s Energy and Chemical Equilibrium Gibb’s Energy or Free Energy: Gibb’s energy or free energy is a thermodynamic function which helps us in the development of a criterion of spontaneity or feasibility of a process. It refers to the capacity of the system to do useful work. Gibb’s […]

Chemical Equilibrium

Science > Chemistry > Chemical Equilibrium > Chemical Equilibrium Rate of a Chemical Reaction: Rate of reaction is the quantities of the reactants converted into the products in unit time. Or Number of moles of the reactants used up or the number of moles of the products formed per unit time. Mathematically it can […]

Physical Equilibrium

Science > Chemistry > Chemical Equilibrium > Physical Equilibrium There are two types of equilibrium: a) physical equilibrium and b) chemical equilibrium. In this article, we shall study physical equilibrium. State of Equilibrium: In many chemical reactions, it is observed that they do not proceed to completion when they are carried out in a closed […]
