planck constant value

where 'h' is proportionality constant, universally referred to as Planck's constant. It has a fixed value of: h = 6.63 x 10 3 4 joule.sec or h = 3.99 x 10 - 1 3 kJ sec mol - 1 . This relation was found to be valid for all types of electromagnetic radiation. T..

The concentration ratio, i.e., the ratio of the product of concentration of the products to that of the reactants at any time (t) is known as the concentration quotient 'Q' of the reaction at time (t). The value of Q c or Q p will be different from the value of K c or K..

In mathematical sense, equilibrium constant is not a constant. It is called constant because at a fixed temperature and pressure, the value of the equilibrium constant for a reaction is constant. The unit of equilibrium constant..

Characteristics of Equilibrium Constant - Some main characteristics of equilibrium constant are described below: The value of the equilibrium constant of a reaction is the same, at constant 'T' and 'P'. However, if either temperature 'T' or pressure..

The magnitude of equilibrium constant K is a measure of the extent to which the reversible reaction has proceeded at equilibrium. The larger the value of the equilibrium constant, the greater is the extent to which the forward reaction takes place and therefore the gre..

The concentration ratio, i.e., the ratio of the product of concentration of the products to that of the reactants at any time (t) is known as the concentration quotient 'Q' of the reaction at time (t). The value of Q c or Q p will be different from the value of K c or K p if the..

The mathematical form of Newton's Law of Gravitation is If m 1 = m 2 = 1, d = 1, then or F = G Hence universal gravitational constant may be defined as the force of gravitation existing between two unit masses separated by unit distance. SI unit of gravitational constant SI unit..

The solar constant is defined as the amount of heat energy received per second per unit area by a perfect black body placed at the surface of the Earth with its surface being held perpendicular to the direction of the sun's rays. The value of solar constant is 1388 Wm ..

In mathematical sense, equilibrium constant is not a constant. It is called constant because at a fixed temperature and pressure, the value of the equilibrium constant for a reaction is constant. The unit of equilibrium constant..
