Problem
20% surface sites have adsorbed N2. On heating N2 gas is evolved from sites and were collected at 0.001 atm and 298 K in a container of volume 2.46 cm3. Density of surface sites is 6.023×1014 cm-2 and surface area is 1000 cm2. Find out the number of surface sites occupied per molecule of N2.
