A given surface of an adsorbent does not show any prefence for physical adsorption of a particular gar because the vander Waals' forceS are

Specific surface area of a solid adsorbent is the surface area of the unit mass of the adsorbent. For any adsorbent, the specific surface area may be increased by taking the adsorbent in powdered form or by increasing the pores in the solid. 112 cm^(3) hydrogen gas is adsorbed uniformly at the surface of 5 gm palladium at 273^(@)C and 2 atm. If the effective surface area of each hydrogen molecule is 0.4 nm^(2) , then the specific surface area of palladium is : [Take : N_(A) = 6x10^(23) ]

Specific surface area of a solid adsorbent is the surface area of the unit mass of the adsorbent. For any adsorbent, the specific surface area may be increased by taking the adsorbent in powdered form or by increasing the pores in the solid. If unit mass of a solid, taken as cube of volume 8 cm^(3) , is powdered into identical 10^(12) cubes, then the specific surface area of the solid increased by :
