Law of Mass Action

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 […]

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 […]

sp3 Hybridization

Science > Chemistry > Physical Chemistry > Nature of Chemical Bond > sp3 Hybridization The mixing of one s-orbital and three p- orbitals of the same atom having nearly the same energy to form four orbitals of equal in all respects and tetrahedrally arranged is known as sp3 hybridization. Geometry of sp3 Hybridization: sp3 hybridized orbitals […]

Hybridization of Orbitals

Science > Chemistry > Physical Chemistry > Nature of Chemical Bond > Hybridization of Orbitals In this article, we shall study the concept of hybridization of orbitals. This concept overcomes the limitations of valence bond theory. Need for Hybridization Concept: A simple approach based on the overlap of s and p orbitals can be applied […]

Valence Bond Theory

Science > Chemistry > Physical Chemistry > Nature of Chemical Bond > Valence Bond Theory Valence bond theory was proposed by Heitler and London in (1927) and it was extended by Pauling and Slater (1931). It is based on the following concepts. The pairing of electrons. Neutralization of opposite electron spins. Overlapping of orbitals containing […]
