changing the position of equilibrium

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 posit..

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 parameters may ..

Addition of an inert gas into a system at equilibrium under constant volume causes, an increase in the pressure of the system, an increase in the total number of moles in the system. Total pressure of a system is then given by, P total V = n total RT or..

Equilibrium between a liquid and its vapours can be represented by the equation...

.e., a to and fro motion. A given point in the path is crossed by the body in opposite directions at regular intervals. This is called oscillatory motion. All oscillatory motions are periodic but not all periodic motions are oscillatory. On observing an oscillating system, like a loaded spring, one..

Elasticity and Deforming Forces - External forces acting on a body, bring about a change in its state or configuration. The latter is possible when the body is not free to move, but the molecules are compelled to change their positions. Such forces are called deforming..

When a steady current passes through a moving coil galvanometer, the coil undergoes a torque and does not come to equilibrium position instantly. Hence the coil is wound over a metallic frame so that the eddy currents produced in the frame can damp the oscillation and brin..

The maximum displacement of the particle executing SHM from the equilibrium position is known as the amplitude. It will be equal to the radius of the circle of reference. Therefore, the total range of motion is ..

The free energy change, D G provides the overall criterion for the feasibility of a chemical process. It gives the balance of the two tendencies, D H and T D S as: D G = D H - T D S Even, if the reaction is not favored energetically (endothermic reaction), the driving force may be pr..

Characteristics of SHM - It is a motion along a straight line. The body moves back and forth with respect to a mean position. The body returns to a given point in the path with the same velocity after regular intervals of time. The acceleration is directly proportional to its displacement from..
