Answer:

The correct answer is option B.

Explanation:

$3NaOH+2NBr_3\rightarrow 3HOBr+3NaBr+N_2$

Moles of $NBr_3$ = 40 mol

Moles of NaOH = 48 mol

According to reaction, 3 moles of NaOH reacts with 2 moles $NBr_3$

Then ,48 moles of NaOH will reacts with:

$\frac{2}{3}\times 48 mol=32 mol$ of $NBr_3$

Then ,40 moles of $NaBr_3$ will reacts with:

$\frac{3}{2}\times 40 mol=60 mol$ of NaOH

As we can see that 48 moles of sodium will completey react with 32 moles of nitrogen tribromide.

Moles left after reaction = 40 mol - 32 mol = 8 mol

Hence, the $NBr_3$ is an excessive reagent.
