Question

The reactant which is entirely consumed in reaction is known as limiting reagent. In the reaction 2A + 4B → 3C + 4D, when 5 moles of A react with 6 moles of B, then(i) which is the limiting reagent?​

Answer 1

Given :- Reaction is given as : $2A+4B$→$3C+4D$

5 moles of A react with 6 moles of B

Above statement can be written in mathematical form : i.e.

$2A=5$ moles

$4B=6$ moles

As $5$ moles of A requires $10$ moles of B but only $6$ moles are present.

Therefore the limiting reagent is B.
