Chapter 16, Problem 16C.2BE

(i)

Interpretation Introduction

Interpretation:

The molar concentration of iodine molecules at $5\text{cm}$ above the real layer after $\text{10}\text{s}$ has to be stated.

Concept introduction:

The migration of any substance from the region of high concentration to the region of low concentration is known as diffusion.  The diffusion process takes place in the liquid and gaseous state.  The diffusion coefficient is denoted by $D$.

(ii)

Interpretation Introduction

Interpretation:

The molar concentration of iodine molecules at $5\text{cm}$ above the real layer after $\text{24}\text{h}$ has to be stated.

Concept introduction:

The migration of any substance from the region of high concentration to the region of low concentration is known as diffusion.  The diffusion process takes place in the liquid and gaseous state.  The diffusion coefficient is denoted by $D$.
