20% of surface sites are occupied by N2 molecules. The density of surf – InterviewSolution

1.	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.
Answer» $20 %$ of surface sites are occupied by $N_{2}$ molecules. The density of surface site is $6.023 \times 10^{14} c m^{- 2}$ and total surface area is $1000 c m^{2}$ . The catalyst is heated to $300 K$ while $N_{2}$ is completely desorbed into a pressure of $0.001 a t m$ and volume of $2.46 c m^{3}$ . Find the number of active sites occupied by each $N_{2}$ molecule.
