Chapter 6, Problem 6B.1ST

Interpretation Introduction

Interpretation:

The standard reaction enthalpy for the reaction ${\text{2SO}}_{\text{2}}\left(\text{g}\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons {\text{2SO}}_{\text{3}}\left(\text{g}\right)$ at temperature $\text{500}\text{K}$ has to be estimated.

Concept Introduction:

The equilibrium constant of a reaction is a parameter which depends only on the temperature of the system.  It is dimensionless as it is calculated from the ratio of activities of the components which are also dimensionless.
