Question

which direction does this reaction shift when so₃ is removed? 2so₂(g) + o₂(g) ⇌ 2so₃(g) + 198 kj the reaction shifts right or to products. the reaction shifts left or to reactants. the reaction does not shift.

Explanation:

Step1: Recall Le Chatelier's Principle

Le Chatelier's Principle states that if a stress is applied to a system at equilibrium, the system will shift in a direction to counteract that stress. Here, the stress is the removal of \( \text{SO}_3 \) (a product).

Step2: Determine the Shift Direction

When a product (\( \text{SO}_3 \)) is removed, the system will try to produce more of the product to counteract the removal. In the reaction \( 2\text{SO}_2(\text{g}) + \text{O}_2(\text{g})
ightleftharpoons 2\text{SO}_3(\text{g}) + 198 \text{kJ} \), producing more product means the reaction will shift to the right (towards the products) to make more \( \text{SO}_3 \).

Answer:

The reaction shifts right or to products.
