Chapter 5, Problem 109E

Interpretation Introduction

Interpretation: The average kinetic energy of ${\text{CH}}_{\text{4}}\left(\text{g}\right)$ and ${\text{N}}_{\text{2}}\left(\text{g}\right)$ molecules should be determined.

Concept introduction:

Kinetic molecular theory explains the properties of ideal gas. From the postulates of kinetic molecular theory it is clear that kinetic energy of gas particle is directly proportional to the Kelvin temperature of the gas.

Average kinetic energy of gas can be determined as,  $K{E}_{avg}=\left(3/2\right)RT$
