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)`]

Options

A. `1.2xx10^(7)cm^(2)//gm`

C. `6.0xx10^(7)cm^(2)//gm`
D. `0.6xx10^(6)cm^(2)//gm`

Answer

B
