which direction does this reaction shift when o2 is added to the solution? 2so2(g) + o2(g) ⇌ 2so3(g) + 198 kj\nthe reaction shifts left or to reactants.\nthe reaction does not shift.\nthe reaction shifts right or to products.
Answer
Explanation:
Step1: Recall Le - Chatelier's principle
When a stress is applied to a system at equilibrium, the system will shift to relieve the stress.
Step2: Analyze the addition of O₂
O₂ is a reactant in the reaction (2SO_{2}(g)+O_{2}(g)\rightleftharpoons 2SO_{3}(g)+ 198\ kJ). Adding more O₂ increases the concentration of a reactant.
Step3: Determine the shift direction
To relieve the stress of increased reactant concentration, the system will shift to the right (towards the products) to consume the added O₂.
Answer:
The reaction shifts right or to products.
