The ratio of this quantity to its “apparent” value defines a quantity symbolized r in the Wenzel and Cassie-Baxter models. Materials with very high values of the specific form of this extensive quantity, like NU-110 and DUT-60, can be activated with supercritical CO2. This quantity can be determined by injecting nitrogen into a sample cell at several different pressures, and then using the B·E·T isotherm. (-5[1])The increased capacitance of EDLCs is due to high values of this quantity for (*) activated carbon electrodes. The (10[1])surface free energy equals the surface tension times this quantity. Catalysts like zeolites (10[1])have high values (-5[1])of this quantity (10[1])due to their extensive pore networks (10[1])giving them (10[2])more sites for reactions to occur. (10[4])For 10 points, give this quantity that measures the space available for molecules (10[1])to adsorb. (10[2])■END■ (10[3]0[2])
