How many moles of CO can be obtained by reacting 2-0 mole of CH4 with 2-0 mole of 02 according to the equation given below? CH4(g) + ~02 —» CO + 2H2

The reaction provided is CH4(g) + 1/2 O2(g) → CO(g) + 2H2(g). According to the stoichiometry of this balanced equation, 1 mole of methane (CH4) reacts with 0.5 moles of oxygen (O2) to produce 1 mole of carbon monoxide (CO). To determine the product yield, we must identify the limiting reagent. We are given 2.0 moles of CH4 and 2.0 moles of O2. For 2.0 moles of CH4, only 1.0 mole of O2 is required (since the ratio is 1:0.5). Since we have 2.0 moles of O2 available, O2 is in excess and CH4 is the limiting reagent. Based on the 1:1 molar ratio between CH4 and CO, the 2.0 moles of CH4 will produce exactly 2.0 moles of CO. Therefore, the maximum amount of CO obtainable is 2.0 moles.
