Given the following N2 adsorption isotherm data for a catalyst supported on Al2O3, do the following: a) Estimate the BET surface area of the catalyst b) Determine the total pore volume of the catalyst, assuming that all pores are filled with liquid Nz when P/Po = 0.995. c) Estimate the average pore diameter assuming uniform cylindrical pores. d) Calculate the catalyst porosity Note: The molar volume of liquid N2 at 77K is 34.7 cm/mole. The density of the solid Al2O3 is 3.95 g/cm Data N2 adsorption po 760 Relative Volume Press Adsorbed ADSORPTION p/po Va mmol/g 0.010 5.572 0.033 5.983 0.065 6.220 0.101 6.389 0.162 6.596 0.181 6.654 0.201 6.712 0.302 6.971 0.500 7.264 0.601 7.402 0.701 7.594 0.801 7.903 0.924 8.856 0.951 9.342 0.995 10.361
