See more Kinetic diameter is a measure applied to atoms and molecules that expresses the likelihood that a molecule in a gas will collide with another molecule. It is an indication of the size of the molecule as a target. The kinetic … See more Collisions between two dissimilar particles occur when a beam of fast particles is fired into a gas consisting of another type of particle, or two dissimilar molecules randomly collide in … See more • Breck, Donald W., "Zeolite Molecular Sieves: Structure, Chemistry, and Use", New York: Wiley, 1974 ISBN 0471099856. • Freude, D., … See more Webb) ZSL. The adsorption kinetic behavior at 0, 20, 60, and 100 °C on the ZSL sample for N 2 O is presented in Figure 3.These results show that the adsorbed amount and the adsorption rate diminish with increasing temperature, as in the case of the ZAPS sample. It can be seen that the adsorbed amounts of N 2 O on the ZSL sample is lower than that on the
