according to the kinetic theory, gases consist of particles thathave motion that is constant, random, and rapid. occupy considerable volume. exert attractive and repulsive forces on other particles. are relatively close together.

Have motion that is constant, random, and rapid.

Explanation:

A is correct. This is one of the postulates of the Kinetic Molecular Theory.

B is wrong. The molecules of an ideal gas have a negligible volume.

C is wrong. The molecules of an ideal gas exert no attractive or repulsive forces on each other.

D is wrong. The molecules of an ideal gas are far apart from each other.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
