Question:
The rate of disappearance of hydrogen \((\text{H}_2)\) from the reaction
\[
\text{N}_2(g) + 3\text{H}_2(g) \rightarrow 2\text{NH}_3(g)
\]
is \(6\, \text{g L}^{-1}\text{s}^{-1}\). The rate of production of ammonia \((\text{NH}_3)\) in \(\text{g L}^{-1}\text{s}^{-1}\) is:

The Correct Option is B
Solution and Explanation
Step 1: Use stoichiometric ratio.
\(\text{N}_2 + 3 \text{H}_2 \rightarrow 2 \text{NH}_3\) implies \[ \text{Rate of NH}_3 = \frac{2}{3} \times \text{Rate of H}_2 \]
Step 2: Apply given rate.
\[ \text{Rate of NH}_3 = \frac{2}{3} \times 51 \approx 34\, \text{g L}^{-1}\text{s}^{-1} \]
Step 3: Final conclusion.
\[ \boxed{34\, \text{g L}^{-1}\text{s}^{-1}} \]

\[ \text{Rate of NH}_3 = \frac{2}{3} \times 51 \approx 34\, \text{g L}^{-1}\text{s}^{-1} \]
Step 3: Final conclusion.
\[ \boxed{34\, \text{g L}^{-1}\text{s}^{-1}} \]
