Calculate the surface area of a catalyst that adsorbs 103 cm3 of nitro...
To solve this problem, we need to use the equation for monolayer coverage:
θ = (V/M) / A
where:
θ = monolayer coverage (in molecules/atom)
V = volume of gas adsorbed (in cm3/g)
M = molecular weight of gas
A = surface area of catalyst (in cm2/g)
Since we are given that the catalyst adsorbs 103 cm3 of nitrogen per gram, we can plug in these values:
θ = (103/28) / A
where the molecular weight of nitrogen is 28 g/mol. Solving for A, we get:
A = (103/28) / θ
To find θ, we need to convert the effective area occupied by a nitrogen molecule on the surface into square centimeters. Since the question gives us this value as 1.62 Å2, we need to convert Å2 into cm2:
1 Å = 10^-8 cm
1 Å2 = 10^-16 cm2
Therefore, 1.62 Å2 = 1.62 x 10^-16 cm2. We can now use this value to calculate θ:
θ = A / (1.62 x 10^-16)
Substituting this into our equation for A, we get:
A = (103/28) / (A / (1.62 x 10^-16))
Simplifying this equation, we get:
A^2 = (103/28) / (1.62 x 10^-16)
A = √[(103/28) / (1.62 x 10^-16)]
A = 7.63 x 10^11 cm2/g
Therefore, the surface area of the catalyst that adsorbs 103 cm3 of nitrogen reduced to STP per gram in order to form the monolayer is approximately 7.63 x 10^11 cm2/g.
