Chapter 6, Problem 79E

Interpretation Introduction

Interpretation:

The average kinetic energy of oxygen gas at 298 K and 1.00 atm should be calculated.

Concept introduction:

The average kinetic energy of gas particles indicates the average value of energy of gaseous particles. It has direct relationship with temperature.

It can be represented as:

$\text{Ek = }\frac{\text{3}}{\text{2}}\left(\frac{\text{RT}}{\text{Na}}\right)$

Here:

E = energy (J)

R= gas constant (8.314 J/K.mol)

T = Temperature (K)

Na = Avogadro number ( $\text{6}\text{.022 }\times {\text{ 10}}^{\text{23}}$ atoms/mole)
