Answer #1

From the equation its clear that 1 mole of HCl require 1 mole of KOH for the reaction to proceede. Limiting reactant is the substance that will be consumed fully in a chemical reaction and whose amount will limit the amount of product formed.

No. of moles = weight given / Molecular weight

No. of moles of HCl = 2.91 moles

No. of moles of KOH = 0.062 moles

NO . of moles of KOH for 2.91 moles of HCl = 2.91 moles

But its lesser than the given one, so KOH is limiting reactant here.
