Calculation of Surface Area of Catalyst
Given:
Volume of nitrogen adsorbed = 103 cm3/g
Effective area occupied by N2 molecule on the surface = 1.62 x 1015 cm2
To calculate the surface area of the catalyst, we need to use the following formula:
Surface area of the catalyst = Volume of nitrogen adsorbed / Effective area occupied by N2 molecule on the surface
Substituting the given values, we get:
Surface area of the catalyst = 103 cm3/g / 1.62 x 1015 cm2
Surface area of the catalyst = 6.39 x 10-10 g/cm
To convert the surface area to square meters, we need to multiply it by 10-4. Therefore,
Surface area of the catalyst = 6.39 x 10-10 g/cm x 10-4 m2/cm2
Surface area of the catalyst = 6.39 x 10-14 m2/g
Now, to convert the surface area to square centimeters, we need to multiply it by 106. Therefore,
Surface area of the catalyst = 6.39 x 10-14 m2/g x 106 cm2/m2
Surface area of the catalyst = 6.39 x 10-8 cm2/g
Rounding off the value to the nearest whole number, we get:
Surface area of the catalyst = 4350 cm2/g
Therefore, the surface area of the catalyst is 4350 cm2/g.
