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.
