Chapter 15, Problem 72E

Interpretation Introduction

Interpretation:

The effect of given changes of temperature on equilibrium state of following endothermic reaction is to be predicted.

${\text{I}}_{\text{2}}\left(\text{g}\right)\underset{}{\overset{}{\rightleftarrows }}\text{ 2I}\left(\text{g}\right)$

Concept Introduction:

Temperature changes mean the flow of heat changes.

In case of an endothermic reaction, heat is absorbed by the reaction mixture. And the change in enthalpy is positive for an endothermic reaction $\left(\text{Δ H > 0}\right)$.
