In physisorption , the molecules of adsorbate held to the adsorbent by

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) ]

How many specific heat does a gas passes?

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 :
