Identifying Limiting Reagent: A+B2 --> AB2

[babita]

Homework Statement

IN A REACTION
A + B2 --> AB2

IF 2 mol A and 3 mol B is taken identify the limiting reagent.

Homework Equations

3 mol B means 1.5 mol of B2 which would react with 1.5 mol of A and 0.5 mol of A will be left
and hence l.r is B
the book says A.
help please

The Attempt at a Solution

Could be the book assumes 3 moles of B₂, but it is not what is stated in the question. 3 moles of B and 3 moles of B₂ are different things and question should be clear on that. For me your answer is the right one.
