Doubt & Answer Explanation

Doubt

when one mole of CO and O2 are made to react at STP, the total no. of moles at the end of the reaction is

Answer Explanation

2 moles of CO react with 1 mole of O2 to form 2 moles of CO2.

But 1 mole of CO and 1 mole of O2 are present. Now 1 mole of O2 requires 2 moles of CO to react and 1 mole of CO requires 0.5 moles of O2 to react. 2 moles of CO are not present but 0.5 moles of O2 are present.

Therefore 1 mole of CO will react with 0.5 moles of O2 to form 1 mole of CO2. 0.5 moles of O2 will remain unreacted. In this reaction CO is the limiting reagent because it limits the quantity of the product formed.

Finally the total moles present are 0.5 (moles of O2) + 1 (mole of CO2) = 1.5.
