Question

Express the rate of the following reaction in terms of the formation of ammonia :

N₂(g) + 3H₂(g) → 2 NH₃(g)

Answer 1

N₂ + 3H₂ → 2NH₃

The rate of reaction can be represented as:

Rate = \(\frac{-d[N_2]}{dt} = - \frac 13 \frac{d[H_2]}{dt} = + \frac 12 \frac{d[NH_3]}{dt}\)

\(\frac{-d[N_2]}{dt} = -\frac 12 (2\times 10^{-2})\)

\(\frac{-d[N_2]}{dt} = 10^{-2} \) mol / dm³ / s

Answer 2

Rate of the reaction.
