An amount of 5 moles of A,\text{A,} 6 moles of B\text{B} and excess amount of C\mathrm{C} are mixed to produce a final product D\mathrm{D}, according to the following reactions.

A+2B→II+C→B+D\begin{aligned} & \mathrm{A}+2 \mathrm{B} \rightarrow \mathrm{I} \\ & \mathrm{I}+\mathrm{C} \rightarrow \mathrm{B}+\mathrm{D} \end{aligned}

What is the maximum moles of D,\mathrm{D}, which can be produced assuming that the products formed can also be reused in the reactions?
View answer and explanation
Correct option: C
5 moles
Option C (5 moles) is correct. Since B is regenerated in the second reaction, A is the limiting reactant, and the maximum moles of D produced will be equal to the initial moles of A.
