le chatelier s principle

The Le Chatelier's principle has a great practical significance for all physical and chemical systems. Applicability of this principle to some of the systems is described bel..

Le Chatelier's Principle - The state of equilibrium in any system depends upon factors present in the system, such as temperature, pressure and concentration of various species. These factors are called reaction variables or parameters. A change in any one of the param..

The state of equilibrium in any system depends upon factors present in the system, such as temperature, pressure and concentration of various species. These factors are called reaction variables or parameters. A change in any one of the parameters may affect the position of the equilibrium. T..

The Aufbau principle states that in the ground state of an atom, an electron enters the orbital of lowest energy first, and then the subsequent electrons are fed in the order of increasing energies into the orbitals. The relative energies of various orbitals are given in fig.1.6. Fr..

Christian Huygen Huygen proposed a hypothesis for the geometrical construction of the position of a common wavefront at any instant during the propagations of waves in a medium. The postulates are: Every point on the given wavefront called 'primary wavefront' acts as a fresh source of new dis..

Uncertainty Principle - All moving objects in our daily life have well defined paths or trajectories. The path or trajectory of an object can be determined by knowing its position and velocity at various intervals of time. However, Werner Heisenberg, in 1927, pointed out that we can never..

The Paulis exclusion principle states, that no two electrons in an atom can have the same values of all the four quantum numbers. If one electron in the atom has the quantum numbers n = 1, l = 0, m = 0 and s = +1/2, no other electron can have the same four quantum numbers. In o..

This principle was proposed by Pauli in 1952. It states that no two electrons in an atom can have same values for all the four quantum numbers. Thus, in the same atom, two electrons may have the same values for three quantum numbers but the fourth must be different. Electrons having the s..
