Question
20% of surface sites are occupied by N2 molecules. The density of surface site is 6.023×1014 cm−2 and total surface area is 1000 cm2. The catalyst is heated to 300 K while N2 is completely desorbed into a pressure of 0.001 atm and volume of 2.46 cm3. Find the number of active sites occupied by each N2 molecule.
