Question

Which of the following is a measure of the average kinetic energy of the particles in a sample of matter? A. Chemical kinetics B. thermochemistryC. reaction rateD. temperature

Answer 1

D. Temperature

Step-by-step explanation:

The temperature of a substance is directly proportional to the average kinetic energy of the particles in the substance according to the equation (valid for monoatomic gases)

`E_K = (3)/(2)kT`

where

Ek is the average kinetic energy

k is the Boltzmann's constant

T is the temperature

From the equation, we see that the temperarure is directly proportional to the average kinetic energy, so the correct answer is

D. temperature
