Science > Chemistry > Surface Chemistry > Factors Affecting Adsorption In last article, we have studied the meaning of terms like adsorption, absorption, adsorbate, adsorbent. In this article, we shall study the factors affecting adsorption. The Extent of Adsorption: The quantity of an adsorbate that is adsorbed per unit mass of adsorbent is called extent […]
Science > Chemistry > Surface Chemistry > Adsorption Adsorption is defined as the phenomenon in which there is the accumulation of one substance on the surface of the other substance. It can also be defined as the change in concentration at the interfacial layer between two phases of the system due to surface forces. OR It […]
Science > Chemistry > Chemical Equilibrium > Applications of Le-Chatelier’s Principle In this article we shall study the application of Le-Chatelier’s principle in Haber’s process, contact proces, etc. Statement of Le-Chatelier’s Principle: This principle is given by, a French chemist Le-Chatelier in 1888. It states that “If an external stress is applied to a reacting […]
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 […]
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 […]
Science > Chemistry > Chemical Equilibrium > Writing Expression for Equilibrium Constant In this article, we shall stuudy to write expression for equilibrium constant. Steps Involved in Writing Expression for Equilibrium Constant of a Reaction: Write the balanced chemical equation for the reaction. Write the products of equilibrium concentrations of the products in the numerator. […]
Science > Chemistry > Chemical Equilibrium > More Examples of Physical Equilibrium In this article, we shall study more examples of physical equilibrim and the dynamic nature of equilibrium. Dissolution of solids in liquids: It is not possible to dissolve just any amount of a solute in a given amount of solvent. A stage will […]
Science > Chemistry > Chemical Equilibrium > Law of Mass Action In this article, we shall study the law of mass action and its application to chemical equlibrium. Rate of Chemical Reaction: The change in the concentration of the reactants (or products) per unit time is called the rate of reaction Mathematically it can be […]
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 […]
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 […]
