The reaction is : A2 +3B22AB3
From the reaction equation, we can say that 1 mol of A2 reacts with 3 moles of B2 to produce 2 moles of AB3.
As given in the figure there are 6 molecules of A2 and 3 molecules of B2.
So, here 1 molecule of A2 will react with 3 molecules of B2 and will produce 2 molecules of AB3. B2 is the limiting reagent.
Please give a thumbs-up.
Do comment if you have any doubts
Thank you
Best of luck
