Question

four 0.4 mol samples of krypton gas are described in the table below. rank these samples in order of decreasing rate of collisions between atoms and the walls of the container.
that is, select \1\ next to the sample with the most collisions per second between kr atoms and the walls of the container. select \2\ next to the sample with the next most collisions per second between kr atoms and the walls of the container, and so on.

Explanation:

Step1: Compare samples with same volume

For samples with the same volume (A and C), higher temperature means higher kinetic energy and more collisions. Since \(T_{C}=- 25^{\circ}C>T_{A}=-47^{\circ}C\), sample C has more collisions than sample A.

Step2: Compare samples with same temperature

For samples with the same temperature (\(T = - 25^{\circ}C\) for B, C, D), smaller volume means higher pressure (more collisions). \(V_{D}=23L

Answer:

D: 1, B: 2, C: 3, A: 4
