Chapter 34, Problem 34.24NP

(a)

Interpretation Introduction

Interpretation:

How to use $\eta \left(T\right)=A{e}^{E/RT}$ equation to calculate constants $A\text{ and }E$ needs to be explained.

Concept Introduction :

Take the logarithm on both the sides of the given equation $\eta \left(T\right)=A{e}^{E/RT}$ to convert it to an equation of a straight line $y=mx+C$ .

(b)

Interpretation Introduction

Interpretation:

Constants $A\text{ and }E$ should be determined for benzene using the given data in the table.

Concept Introduction :

A linear equation in the form of $y=mx+C$ is plotted using values of viscosity $\eta \left(T\right)$ and the corresponding temperature $T$ . The equation $y=mx+C$ is compared to the equation $\ln \left[\eta \left(T\right)\right]=\frac{E}{RT}+\ln \left(A\right)$ , which can then be used to find out the constants $A\text{ and }E$ .
