value of planck`s constant

E.g., gravitational constant (G), Planck's constant (h) and velocity of light (c) Their values are always constant..

The value of the equilibrium constant of a reaction is the same, at constant 'T' and 'P'. However, if either temperature 'T' or pressure 'P' or both are changed, the value of the equilibrium constant may also change. For example, the value..

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 'P' or both are changed, the value of the..

Reaction Quotient and the Equilibrium Constant - 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..

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 of..

Solar Constant (S) - 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..

Units of Equilibrium Constant - 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. T..

Consider a reversible reaction expressed by the following general equation: where A and B are two substances which react to form new substances C and D and C and D react under the same conditions forming the original substances A and B. Let us assume that the concentrations of these four substances..
