To reiterate the problem, we are asked to find which of the reactants is the limiting one. The reaction is
CH₄ + 2 O₂ → CO₂ + 2 H₂O
We have an initial amount of 3.05 mol CH₄. Let's see how much of oxygen is required for this:
Theoretical mol O₂ required = 3.05 mol CH₄ * 2 mol O₂/1 mol CH₄ = 6.1 mol
However, the initial amount of oxygen is only 5.03 mol, which is not enough for the theoretical value. Therefore, the limiting reactant is oxygen.
