For the reaction`N_2 (g) + 3H_2 (g) to 2NH_3 (g)`
How is the rate of formation of ammonia related to the rate of disappearance of `H_2` ?

Explanation

To find the relationship between the rate of formation of ammonia (NH₃) and the rate of disappearance of hydrogen (H₂) for the reaction:

\[ N_2 (g) + 3H_2 (g) \rightarrow 2NH_3 (g) \]

we can use the concept of stoichiometry in chemical kinetics.
