Question

The reaction between nitrogen and hydrogen to produce ammonia is described as an equilibrium reaction. what substances are present in the reaction mixture when equilibrium has been obtained?

Answer 1

Below is to complete the question above:

3H₂ + N₂ ⇌ 2NH₃

a.NH₃
b.N₂
c.H₂
d.NH₄+

The answer is:

a,b, and c.

H₂,N₂, and NH₃ are the only reactants and products and are thus present when equilibrium has been attained

Answer 2

Explanation:

An equilibrium reaction is defined as the reaction in which the rate of forward reaction is equal to the rate of backward reaction.

For example, an equilibrium reaction between nitrogen, hydrogen and ammonia will be as follows.

           $N_{2} + H_{2} \rightleftharpoons NH_{3}$

Also, in an equilibrium mixture both reactants and products remain in the reaction mixture.

Therefore, we can conclude that in the given reaction mixture when equilibrium has been obtained then substances present in it will be $N_{2}$, $H_{2}$ and $NH_{3}$.
