In the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g), what happens if the temperature is increased?
Correct Answer: Equilibrium shifts to the left, favoring SO2 and O2.
- Step 1: Identify the type of reaction. The given reaction is 2SO2(g) + O2(g) ⇌ 2SO3(g).
- Step 2: Determine if the reaction is exothermic or endothermic. An exothermic reaction releases heat.
- Step 3: If the reaction is exothermic, increasing the temperature adds heat to the system.
- Step 4: According to Le Chatelier's principle, the system will try to counteract the added heat.
- Step 5: To counteract the heat, the equilibrium will shift to the left, favoring the reactants (SO2 and O2).
- Step 6: Therefore, increasing the temperature will result in more SO2 and O2 being produced.
