Answer:
From the balanced equation for the reaction we can find that
4 atoms of A require 3 gram molecules of B4
Therefore 2 atoms of require=2×3÷4 =6÷4 =1.5
But we have 2 gram molecule of B4 in a place where 1.5 is only needed B4 is in excess and the reaction is stopped only by the limitation of A2, therefore A2 is the limiting reagent.
