Introduction to Le Chatelier's Principle

For a reactio...

Question

For a reaction, $2 N H_{3} ⟶ N_{2} + 3 H_{2}$ , it is observed that:

$\frac{- d [N H_{3}]}{d t} = k_{1} [N H_{3}], \frac{d [N_{2}]}{d t} = k_{2} [N H_{3}], \frac{d [H_{2}]}{d t} = k_{3} [N H_{3}]$ .

What is the relation between $k_{1}, k_{2}$ and $k_{3}$ ?

A

k_{1} = k_{2} = k_{3}
