Chapter 6, Problem 6.137QP

(a)

Interpretation Introduction

Interpretation: The relative rates of diffusion of ${}^{\text{13}}{\text{CO}}_{\text{2}}$ and ${}^{\text{12}}{\text{CO}}_{\text{2}}$ are to be calculated and a gas that diffuses faster is to be predicted.

Concept introduction: The Graham’s law of diffusion states that, “the rate of diffusion of gaseous molecules is inversely proportional to the square root of its molar mass of the gas molecules”.

$r\propto \frac{1}{\sqrt{m}}$

To determine: The relative rates of diffusion of ${}^{\text{13}}{\text{CO}}_{\text{2}}$ and ${}^{\text{12}}{\text{CO}}_{\text{2}}$.

(b)

Interpretation Introduction

To determine: The gas that diffuses faster.
