The ratio of this quantity to its “apparent” value defines a quantity symbolized r in the Wenzel and Cassie-Baxter models. Supercritical CO2 is used to activate materials with very high values of the specific (-5[1])form of this quantity, like NU-110 and DUT-60. This quantity (-5[1])can be determined by injecting nitrogen into a sample cell at (-5[1])several different (-5[1])pressures, and then using the B·E·T isotherm. (15[1]-5[1])The increased capacitance of EDLCs is due to high values of this quantity (-5[1])for (*) activated carbon electrodes. (10[1])The surface free energy equals the surface tension times this quantity. Catalysts like zeolites have high (10[1])values of this quantity (10[1]-5[1])due to their (10[1])extensive pore networks (10[1])giving them (10[1])more (10[1])sites for (10[1])reactions (10[1])to occur. For 10 points, give this quantity that measures the space available for molecules to adsorb. ■END■ (10[4]0[2])
