Question

2 moles of A and 3 moles of B react with to form AB. A+B→AB identify the limiting agent in the reaction?
option(a)A
option(b)B
option(c)A as well as B option(d)None​

Answer 1

Answer:

B

Explanation:

A+B->AB

2A+2B->2AB

B is left behind

Answer 2

B is the limiting agent in the reaction in which 2 moles of A and 3 moles of B react to form AB.

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