CH3CH2OH + 302 → 2002 + 3H20 What would be the limiting reactant in the reaction if 1 mole of
oxygen gas and 1 mole of ethanol (CH3CH2OH) reacted with
each other?

Oxygen gas

Explanation:

 Given expression:

          CH₃CH₂OH + 3O₂ → 2CO₂ + 3H₂O

Number of moles of oxygen gas  = 1 mole

Number of moles of ethanol = 1 mole

Unknown:

The limiting reactant  = ?

Solution:

The limiting reactant is the reactant in short supply in a chemical reaction. To find this specie, we always us the number of moles.

  From the equation of the reaction:

        1 mole of ethanol would require 3 moles of oxygen gas

 But we have been given just 1 mole of oxygen gas instead of 3moles.

 Therefore, oxygen gas is the limiting reactant.
