Question

according to collision theory, what is not a factor that determines if two molecules will bind?
a. the direction the molecules are facing.
b. the speed the molecules are traveling.
c. the specific heat of the molecules.
d. what element the molecules are.

Explanation:

Collision theory states that for molecules to bind (react), they must collide with proper orientation (related to direction they are facing - A), sufficient energy (related to speed as kinetic energy \(KE=\frac{1}{2}mv^{2}\) - B), and the nature of the molecules (element they are - D matters as different elements have different reactivity). Specific heat (C) is the amount of heat required to raise the temperature of a substance per unit mass. It is a property related to heat transfer and temperature change of a bulk substance, not a factor in molecular binding according to collision theory.

Answer:

C. The specific heat of the molecules.
