Question

In the chemical reaction,
$N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)$
at equilibrium point:

• A. Equal volumes of $N_2$ and $H_2$ are reacting
• B. Equal masses of $N_2$ and $H_2$ are reacting
• C. The reaction has stopped
• D. The same amount of ammonia is formed as it is decomposed into $N_2$ and $H_2$.

Answer 1

The correct option is D The same amount of ammonia is formed as it is decomposed into $N_2$ and $H_2$.

In a chemical reaction, chemical equilibrium is achieved when the rate of forward reaction is equal to the rate of backward reaction.

Hence when the same amount of ammonia is formed as it is decomposed into $N_2$​ and $H_2$, Then we can say that Equilibrium state has achieved.
