Question

20% surface sites have adsorbed N₂ On heating N₂ gas evolved from sites and were collected at 0.001 atm and 298 K in a container of volume is 2.46 cm³. Density of surface sites is 6.023 x 10¹⁴ and surface area is 1000 cm² find out the number of surface sites occupied per molecule of N₂.

Answer 1

Given that, Density of surface site = 6.023 x 10¹⁴ cm^-2

Total surface area = 1000 cm² 

Total number of surface sites = density x total surface area

= 6.023 x 10¹⁴ x 1000

=  6.023 x 10¹⁷

Sites occupied by nitrogen molecule (20%)

0

Therefore, number of sites occupied by each nitrogen molecules
