Chapter 10, Problem 46PS

Interpretation Introduction

Interpretation: The gases present in the given reaction should be arranged in the order of increasing $\text{rms}$ speed at given temperature.

Concept introduction:

The root mean square velocity $\mu$ is defined as the measure of velocity of particle in gas. It is the method to determine the single velocity value for particles.

Root mean square velocity can be determined,

                                                        ${\mu }_{rms}={\left(\frac{3RT}{M}\right)}^{1/2}$ (1)

  $\begin{array}{l}\left(\text{gas constant}\right)R=\frac{8.314J}{Kmol}\\ M=Molarmass\end{array}$

Molar mass: The molar mass of a substance is determined by dividing the given mass of substance by the amount of the substance.
