Question

the reaction shifts to the right (products). what happens to the amount of o₂ as the reaction shifts? 2so₂(g) + o₂(g) ⇌ 2so₃(g) + 198 kj the amount of o₂ goes down. the amount of o₂ does not change. the amount of o₂ goes up.

Explanation:

In the reaction \(2SO_2(g)+O_2(g)
ightleftharpoons 2SO_3(g)+198\ kJ\), when the reaction shifts to the right (towards products), the reactants are consumed to form products. \(O_2\) is a reactant, so as the reaction proceeds to the right, \(O_2\) is used up, leading to a decrease in its amount.

Answer:

The amount of \(O_2\) goes down.
