Adsorption: ConcepTest and Example Problem
Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.
Example Problem 1
Two measurements of N2 adsorption on charcoal were carried out where the N2 coverage was low. Use these measurements to determine the heat of adsorption of N2 on charcoal:
0.92 cm3/g at 4.8 bar and 190 K
0.92 cm3/g at 32 bar and 250K
