Answer:
KO₂ is limiting reactant
Explanation:
Based on the balanced reaction:
2CO₂ + 4KO₂ → 2K₂CO₃ + 3O₂
2 moles of CO₂ react with 4 moles of KO₂.
Thus, for a complete reacction of 0.25 moles of CO₂ are required:
0.25 moles * (4moles KO₂ / 2moles CO₂) = 0.5 moles of KO₂
As there are just 0.1 moles:
KO₂ is limiting reactant
