The image above represents specific surface area due to coverage. To calculate specific surface area due to coverage, three essential parameters are needed and these parameters are Assumed Total Volume Coverage of Gas (Vm), Surface Energy / Average Area of One Adsorbate Molecule in Complete Monolayer (σ) and Avogadro’s Constant (NA).
The formula for calculating specific surface area due to coverage:
A = VmσNA/22414
Where:
A = Specific Surface Area due to Coverage
Vm = Assumed Total Volume Coverage of Gas
σ = Surface Energy / Average Area of One Adsorbate Molecule in Complete Monolayer
NA = Avogadro’s Constant
Let’s solve an example;
Find the specific surface area due to coverage when the assumed total volume coverage of gas is 4, the surface energy / average area of one adsorbate molecule in complete monolayer is 6 and the avogadro’s constant is 6.023E23.
This implies that;
Vm = Assumed Total Volume Coverage of Gas = 4
σ = Surface Energy / Average Area of One Adsorbate Molecule in Complete Monolayer = 6
NA = Avogadro’s Constant = 6.023E23
A = VmσNA/22414
So, A = (4)(6)(6.023e+23)/22414
A = 1.4455199e+25/22414
A = 644918354599803600000
Therefore, the specific surface area due to coverage is 644918354599803600000 m²/g.
