Calculate the surface area of a catalyst that adsorbs 10^3 cm^3 of N_2 (reduced to STP) per gram in order to form the monolayer. The effective area occupied by N_2 molecule on the surface is 1.62 xx 10^5 cm^2

Answer»

`2520 x 10^5 cm^2`
`4350 m^2`
`3720 m^2`
`435 xx 10^5cm^2`

SOLUTION :One MOLECULE area `= 1.62 xx 10^(-15)`
`22400 to 6 xx10^(23)` molecules , `10^3 to ?`
`(6 xx 10^(26))/(22400) "then" (6 xx 10^(26))/(22400) xx 1.62 xx 10^(-15) ` area occupied `= 435 xx 10^(15) a^2`
