The limiting reactant for this reaction is $KOH$.
Work Step by Step
- For an equal quantity of moles, the substance with higher balance coefficient will be the limiting one. This happens because the reaction demands a higher amount of that substante, so it will be the first to be totally consumed. - In this case, the potassium hydroxide $KOH$ has 4 as its coefficient, which is the greater one, making that substance the limiting reactant.
