For the reaction, $2 N H_{3} (g) \to N_{2} (g) + 3 H_{2} (g)$
$- \frac{d [N H_{3}]}{d t} = k_{1} [N H_{3}]$
$\frac{d [N_{2}]}{d t} = k_{2} [N H_{3}]$
$\frac{d [H_{2}]}{d t} = k_{3} [N H_{3}]$
The relation between, $k_{1}, k_{2}$ and $k_{3}$ may be given as

Options:

Answer:

Solution:

for the given reaction,
$- \frac{1}{2} \frac{d [N H_{3}]}{d t} = \frac{d [N_{2}]}{d t} = \frac{1}{3} \frac{d [H_{2}]}{d t}$
$\frac{1}{2} k_{1} = k_{2} = \frac{1}{3} k_{3}$
$1.5 k_{1} = 3 k_{2} = k_{3}$
