Question

2 moles of A and 3 moles of B react to form AB. A+B AB
Identify the limiting reagent in the reaction ?​

Answer 1

Answer:

2 mol A + 3 mol B. Here according to the reaction 1 atom of A reacts with 1 molecule of B. Therefore, 2 mol of A atoms will react with only 2 mol of B molecules, thereby left with 1 mole of B unreacted. Hence, A is the limiting reagent in this reaction.
