UPSC CDS-2 – 2018
For 2.0 moles of CH₄, 2.0 * 0.5 = 1.0 mole of O₂ is required. We have 2.0 moles of O₂, which is more than required. Thus, CH₄ is the limiting reactant.
The amount of product is determined by the limiting reactant. From the equation, 1 mole of CH₄ produces 1 mole of CO. Therefore, 2.0 moles of CH₄ will produce 2.0 moles of CO.
