Per two gram of charcoal, a gas is adsorbed by 0.1 g and 0.2 g at 10 torr and 80 torr pressure respectively. Calculate the n value in Freundlich adsorption isotherm.

The pressure of a gas is 2.5 atm . Calculate the value in torr.

In freundlich adsorption isotherm, the value of 1//n is

The vapour preesure of two pure liquids A and B are 5 and 10 torr respectively. Calculate the total pressure of the solution (in torr) obtained by mixing 2 mole of A and 3 mole of B.

Amount of gas adsorbed per gram of adsorbent increases with pressure, but after a certain limit is reached, adsorption becomes constant. It is where

5 moles of liquid X and 10 moles of liquid Y make a solution having a total vapour pressure 70 torr. The vapour pressures of pure X and pure Y are 64 torr and 76 torr respectively.Calculate the expected pressure.

If x/m is the mass of adsorbate adsorbed per unit mass of adsorbent, P is the pressure of the adsorbate gas ,a and b are constant ,which of the following represent "Langmuir adsorption isotherm"?

The vapour pressure of two pure liquids A and B are 50 and 40 torr respectively. If 8 moles of A is mixed with x moles of B , then vapour pressure of solution obtained is 48 torr. What is the value of x.

Adsorption is the presence of excess concentration of any particular component at the surface of liquid a solid phase as compared to bulk.This is due to presence of residual forces at the surface of body.In the adsorption of hydrogen gas over a sample of charcoal, 1.12cm^3 of H_2(g) measured over S.T.P was found to absorb per gram of charcoal.Consider only monolayer adsorption.Density of H_2 is 0.07gm/cc. In another experiment same 1 gm charcoal adsorbs 100 ml of 0.5M CH_3COOH to form monolayer and thereby the molarity of CH_3COOH reduces to 0.49. ((3xx47.43)/(4pi))^(1//3)=2.24 (2.24)^2=5 Surface area of charcoal adsorbed by each molecule of (acetic soda) is-
