Interpretation Introduction

Interpretation : The $K_{\text{p}}$ at $\text{915 °C}$ should be calculated for the reaction of ${\text{SO}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$ to form ${\text{SO}}_{\text{3}}$ . The $\Delta H_{rxn}\text{= -198}\text{.4 kJ/mol}$ and $K_{\text{p}}$ at $\text{830 °C}$ is $\text{0}\text{.13}$ .

Concept Introduction :

The relation between $\Delta H_{rxn}$ (enthalpy change of reaction) and $K_{\text{p}}$ can be written as:

  $\ln \frac{K_2}{K_1}=\frac{\Delta H_{rxn}}{R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right)$
