A) The equilibrium shifts to the right. B) The equilibrium shifts to the left. C) The equilibrium remains unchanged. D) The reaction rate increases but the equilibrium position remains the same. Answer: B) The equilibrium shifts to the left. Explanation: According to Le Châtelier's principle, increasing temperature favors the endothermic direction of a reaction. Since the given reaction is exothermic, increasing temperature shifts the equilibrium toward the reactants, which is to the left. This example demonstrates the importance of understanding thermodynamics principles and applying Le Châtelier's principle to interpret questions correctly.
