Question
For the reaction : $\text{N}_2\text{(g)}+\text{3H}_2\text{(g)}\rightleftharpoons\text{2NH}_3\text{(g)}$ Equilibrium constant $\text{K}_\text{c}=\frac{[\text{NH}_3]^2}{[\text{N}_2][\text{H}_2]^3}$ Some reactions are written below in Column I and their equilibrium constants in terms of $\text{K}_\text{c}$ are written in Column II. Match the following reactions with the corresponding equilibrium constant.
| Column I (Reaction) | Column II (Equilibrium constant) | ||
| i. | $2\text{N}_2\text{(g)}+\text{6H}_2\text{(g)}\rightleftharpoons\text{4NH}_3\text{(g)}$ | a. | $2\text{K}_\text{c}$ |
| ii. | $2\text{NH}_3\text{(g)}\rightleftharpoons\text{N}_2\text{(g)}+\text{3H}_2\text{(g)}$ | b. | $\text{K}_\text{c}^\frac{1}{2}$ |
| iii. | $\frac{1}{2}\text{N}_2\text{(g)}+\frac{3}{2}\text{H}_2\text{(g)}\rightleftharpoons\text{NH}_3\text{(g)}$ | c. | $\frac{1}{\text{K}_\text{c}}$ |
| d. | $\text{K}_\text{c}^2$ | ||
