CHEM 2710 TUTORIAL #5 (1.) Consider the experimental data given below for the adsorption of N2 on mica at 90K: P(atm) 2.8 3.4 4.0 4.9 6.0 7.3 9.4 12.8 V(cm) 12.0 13.4 15.1 17.0 19.0 21.6 23.9 25.5 V is the volume of gas measured at 20C and 1 atm. (a) Show that the data fits a Langmuir-isotherm expression and evaluate the constants in the expression. (b) Given that the surface area of the mica sample in the Langmuir experiment is 153 m, estimate the area covered by one N2 molecule. (2.) Does the data from question 3 fit a Freundlich-isotherm expression? If so, determine the constants in the expression
