Nitrogen monoxide reacts with oxygen according to the following reaction: 2NO(g)+ O₂(g)→ 2NO₂(g)If 10 moles of nitrogen monoxide are combined with 4 moles of oxygen, how many moles of NO₂ should form?

Question

Quizplus · Accepted Answer

According to the balanced equation, 2 moles of NO react with 1 mole of O2 to form 2 moles of N2O. Therefore, if there are 10 moles of NO and 4 moles of O2, there is not enough O2 to fully react with all of the NO. The limiting reactant will be O2, and there will be 2 moles of N2O formed for every mole of O2 consumed. Therefore, 2 moles of N2O will be formed from the initial 4 moles of O2, and the remaining 6 moles of NO will be unreacted. The total moles of N2O formed will be 2 x 5 = 10 moles.
