Chapter 4, Problem 4.20E

(a)

Interpretation Introduction

Interpretation:

The molar kinetic energy (in joules per mole) of $\text{Ne}\left(\text{g}\right)$ at $\text{25}{\text{.00}}^{\text{o}}\text{C}$ has to be calculated.

Concept Introduction:

The molar kinetic energy is calculated from formula.

  $\text{U=}\frac{\text{3}}{\text{2}}\text{RT}$

Here, $\text{U=}$ Total kinetic energy

  $\text{R=}$ Gas constant $\left(\text{8}\text{.314 J}{\text{mol}}^{\text{-1}}{\text{K}}^{\text{-1}}\right)$

  $\text{T=}$ Temperature (in Kelvin)

(b)

Interpretation Introduction

Interpretation:

The molar kinetic energy (in joules per mole) of $\text{Ne}\left(\text{g}\right)$ at $\text{26}{\text{.00}}^{\text{o}}\text{C}$ has to be calculated.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The value of molar heat capacity of $\text{Ne}\left(\text{g}\right)$ has to be calculated.
