A catalyst adsorb 100 mL of nitrogen gas at S.T.R per gram of catalyst surface and forms a mono-molecular layer. The effective surface area occupied by one nitrogen molecule on the surface of catalyst is 0.16 x 10 -14 cm 2 . What is the total surface area occupied by nitrogen molecules per gram of catalyst? (Given: Volume of gas at STP = 22.4 L)
Text Solution
Verified by ExpertsThe correct answer is:
A
43.04 x 10 5 cm 2
Surface area occupied by one molecule = 0.16x10 -14 cm 2
Total area covered by N 2 (g) /gram of catalyst = 0.16 x 10 -14 x 2.69 x 10 21 = 43.04 x 10 5 cm 2
