Question

Statement-1: $2A+3B\to C$, $\frac{4}{3}$ moles of $C$ are always produced when $3$ moles of $A$ and $4$ moles of $B$ are added.
Statement-2: $B$ is the liming reactant for the given data.

• A. Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
• B. Statement-1 is true, statement-2 is true and statement -2 is NOT the correct explanation for statement-1.
• C. Statement -1 is false, statement-2 is true.
• D. Statement-1 is true, statement-2 is false.

Answer 1

Answer: (A)

Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.

$3$ moles of $A$ will react with $\frac{3\times 3}{2}=4.5$ moles of $B$.
However, only $4$ moles of $B$ are present.
Thus, $B$ is the limiting reagent.
$4$ moles of $B$ will produce $\frac{4}{3}$ moles of $C$.
