Question

Quizplus · Accepted Answer

Since the reaction is endothermic ($\Delta H^\circ_{\text{rxn}}$ = 198 kJ/mol), increasing the temperature shifts the equilibrium to the right (favoring the products) and increases the value of the equilibrium constant $K$, according to Le Chatelier's principle.
