graham's law of diffusion examples with solution

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..

It is a physical process that involves the movement of solute particles from the region of their higher concentration to the region of their lower concentration. Transport of materials within the cell is by diffusion. The entry of carbon dioxide into the stomata is by diff..

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,..

Like gases, liquids also diffuse but they diffuse slowly than the gases. The diffusion of liquids is defined as the process of intermixing of the molecules of two or more liquids to form homogeneous mixture solution. This is also the movement of soluteh..

Experiment 2: Place some crystals of potassium permanganate at the bottom of a beaker. Slowly transfer water into the beaker with the help of a pipette. After sometime a dense purple solution is formed at the bottom and you will notice that it gradually spreads with the rest of water...

Mass of the reactants = 10g Mass of the products = 4.6 + 5.6g = 10g Since the mass of the reactants is equal to the mass of the products, the observations are in agreement with the law of conservation of mas..

By law of conservation of momentum, momentum before collision is equal to momentum after collision. ..

Heat absorbed by the system = 470 J or q = 470 J Work done by the system = 200 J or w = - 200 J According to first law of thermodynamics D E = q + w D E = 470 - 200 = 270 J 3. A gas absorbs 120 J of heat and expands against the external pressure of 1.10atm from a volume of 0.5L to 2.0L..
