To solve the problem, we need to analyze the reaction between sulfur dioxide (SO₂) and oxygen (O₂) to form sulfur trioxide (SO₃). The balanced chemical equation for the reaction is: \[ 2 \text{SO}_2 + \text{O}_2 \rightarrow 2 \text{SO}_3 \] ### Step 1: Determine the stoichiometric requirements From the balanced equation, we can see that: - 2 moles of SO₂ react with 1 mole of O₂ to produce 2 moles of SO₃. ...
