Chapter 8, Problem 12E

Interpretation Introduction

Interpretation: In the reaction:

$\text{A}+\text{2B}\to \text{C}$

If $25g$ of A and $8g$ of B are present and A was completely used up in the reaction while 4 g of B was left. Then, amongst A and B, the limiting reactant is to be identified.

Concept introduction:

A substance which is completely consumed in the reaction to give the product (in the least amount) is known as limiting reactant.

A reagent which is present in smaller amount forms a limiting reagent.
