Chemical Kinetics - Result Question 52
####52. For the reaction : $N _2(g)+3 H _2(g) \longrightarrow 2 NH _3(g)$
Under certain conditions of temperature and partial pressure of the reactants, the rate of formation of $NH _3$ is $0.001 kg / h^{-1}$.
The rate of conversion of $H _2$ under the same condition is …. $kg / h^{-1}$.

Answer:
Correct Answer: 52. $(0)$
Solution:
- $-\frac{1}{3} \frac{d\left[H _2\right]}{d t}=\frac{1}{2} \frac{d\left[NH _3\right]}{d t}$
$\Rightarrow \frac{-d\left[H _2\right]}{d t}=\frac{3}{2} \frac{d\left[NH _3\right]}{d t}=\frac{3}{2} \times 0.001=0.0015 kg h^{-1}$.
