Which is the limiting reactant when 12.0 moles of CH₄ are reacted with 20.0 moles of O₂ in the following equation? CH₄ + 2O₂ $\rarr$ CO₂ + 2H₂O

Question

Quizplus · Accepted Answer

To determine the limiting reactant, we need to compare the number of moles of each reactant to the stoichiometric coefficients in the balanced equation. For CH₄, we need 1 mole to react with 2 moles of O₂, so we would need 24.0 moles of CH₄ to completely react with 20.0 moles of O₂. Since we only have 12.0 moles of CH₄, it is the limiting reactant. Therefore, O₂ is in excess and not a limiting reagent.
