Fill in the Blanks
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. $(0.0015)$
Solution:
- $-\dfrac{1}{3} \dfrac{d\left[H _2\right]}{d t}=\dfrac{1}{2} \dfrac{d\left[NH _3\right]}{d t}$
$\Rightarrow \quad \dfrac{-d\left[H _2\right]}{d t}=\dfrac{3}{2} \dfrac{d\left[NH _3\right]}{d t}=\dfrac{3}{2} \times 0.001=0.0015 $ $kg \hspace {1mm} h^{-1}$.
