Question

For the equilibrium $N_2\left(g\right)+3H_2\left(g\right)\leftrightharpoons 2N{H}_3\left(g\right)$ at ${1000}^{\circ }C$ the equilibrium constant is very low, then which of the following is correct at equilibrium ?

• A. $\left[H_2\right]$ is very high but not $\left[N_2\right]$
• B. $\left[H_2\right]$ is low
• C. $\left[N_2\right]$ is low
• D. $\left[N{H}_3\right]$ is very low

Answer 1

The correct option is D $\left[N{H}_3\right]$ is very low

When the value of the equilibrium constant is very low, the concentration of product is very low.
Thus for very low value of the equilibrium constant, the term $\left[N{H}_3\right]$ has very low value.
