numericals of graham law of diffusion

From kinetic theory, Since the rate of diffusion of a gas is determined by the molecular speed,..

Gases have the tendency to spontaneously intermix and form a homogenous mixture without the help of external agency. This is due to the presence of large amount of empty space between the gas molecules that makes their movement rapid into each other. The gases move from a region of higher concentr..

Kirchhoff's Law - A body that is a good radiator (or emitter) is also a good absorber. To understand this, suppose isotropic (i.e., equal in all directions) thermal radiation is incident on a body. Let a be the fraction of the total thermal radiation of all wavelengths absorbed by the bod..

A.L.Lavoisier and P.S.Laplace gave this law in 1780 which states that 'the enthalpy of a reaction is exactly equal but opposite in sign for the reverse reaction'. For example, if D H is the enthalpy change in going from A to B then the enthalpy change for the process B to A would be - D..

Let the rate of diffusion of oxygen be r(O 2 ) = r 1 The rate of diffusion of the unknown gas r (x) = 4r Molecular mass of O, M(O) = 32 Molecular mass of unknown gas M (x) = M From Graham's Law of diffusion,..

Numerous bars of wrought iron surrounded by carbon are heated in fire-brick boxes to a temperature of around 1000 o C for 10 days. The carbon diffused slowly into iron and converts iron into steel. Carbonisation of the iron bars is obviously more at the surface. This resul..

The V E E supply is used to forward bias emitter base junction. As a result significant current flows, once the potential barrier is exceeded. The majority charge carriers diffuse from emitter into base and this results in emitter current I E as indicated in the above diagram. Once these ..
