20% of the surface sites adsorbed N2. On heating, N2 gas evolves from...
For adsorbed N2 on surface sites,
Now, to find the moles of N2 gas adsorbed using the ideal gas equation:
Molecules of adsorbed,
Surface site density = 6.023 × 1014 cm−2Area of surface site = 1000 cm3Total surface sites available = Number of sites per cm2 × Area
Total surface sites available = 6.023 × 1014 × 1000 = 6.023 × 1017
Surface sites on which N2 is adsorbed = 20% × Available sites

20% of the surface sites adsorbed N2. On heating, N2 gas evolves from...
Given data:
- Surface site density: 6.023 × 10^14 cm^−2
- Percentage of surface sites adsorbed N2: 20%
- Area of surface site: 1000 cm^2
- Pressure of N2 gas evolved: 0.001 atm
- Volume of container: 2.46 cm^3
- Temperature: 298 K
Calculations:
1. Calculate the total number of surface sites:
Total surface sites = Surface site density * Area of surface site
Total surface sites = 6.023 × 10^14 cm^−2 * 1000 cm^2
Total surface sites = 6.023 × 10^17 sites
2. Calculate the number of surface sites adsorbed with N2:
Number of surface sites adsorbed = 20% of total surface sites
Number of surface sites adsorbed = 0.2 * 6.023 × 10^17
Number of surface sites adsorbed = 1.205 × 10^17 sites
3. Calculate the number of moles of N2 evolved:
PV = nRT
n = PV/RT
n = (0.001 atm * 2.46 cm^3) / (0.0821 L.atm/mol.K * 298 K)
n = 1.007 × 10^-5 mol
4. Calculate the number of molecules of N2 evolved:
Number of molecules = n * Avogadro's number
Number of molecules = 1.007 × 10^-5 mol * 6.022 × 10^23 mol^-1
Number of molecules = 6.065 × 10^18 molecules
5. Calculate the number of surface sites occupied per molecule of N2:
Number of surface sites per molecule = Number of surface sites adsorbed / Number of molecules
Number of surface sites per molecule = 1.205 × 10^17 / 6.065 × 10^18
Number of surface sites per molecule ≈ 2
Therefore, the number of surface sites occupied per molecule of N2 is 2.
- Surface site density: 6.023 × 10^14 cm^−2
- Percentage of surface sites adsorbed N2: 20%
- Area of surface site: 1000 cm^2
- Pressure of N2 gas evolved: 0.001 atm
- Volume of container: 2.46 cm^3
- Temperature: 298 K
Calculations:
1. Calculate the total number of surface sites:
Total surface sites = Surface site density * Area of surface site
Total surface sites = 6.023 × 10^14 cm^−2 * 1000 cm^2
Total surface sites = 6.023 × 10^17 sites
2. Calculate the number of surface sites adsorbed with N2:
Number of surface sites adsorbed = 20% of total surface sites
Number of surface sites adsorbed = 0.2 * 6.023 × 10^17
Number of surface sites adsorbed = 1.205 × 10^17 sites
3. Calculate the number of moles of N2 evolved:
PV = nRT
n = PV/RT
n = (0.001 atm * 2.46 cm^3) / (0.0821 L.atm/mol.K * 298 K)
n = 1.007 × 10^-5 mol
4. Calculate the number of molecules of N2 evolved:
Number of molecules = n * Avogadro's number
Number of molecules = 1.007 × 10^-5 mol * 6.022 × 10^23 mol^-1
Number of molecules = 6.065 × 10^18 molecules
5. Calculate the number of surface sites occupied per molecule of N2:
Number of surface sites per molecule = Number of surface sites adsorbed / Number of molecules
Number of surface sites per molecule = 1.205 × 10^17 / 6.065 × 10^18
Number of surface sites per molecule ≈ 2
Therefore, the number of surface sites occupied per molecule of N2 is 2.
