At a given temperature and pressure, the equilibrium constant value for the equilibria are given below:
\(3A_2+B_2\rightleftharpoons 2A_3B, K_1\\ A_3B \rightleftharpoons \frac 3{2}A_2+\frac 1{2}B_2, K_2 \)
The relation between \(K_1\) and \(K_2\) is:
\(3A_2+B_2\rightleftharpoons 2A_3B, K_1\\ A_3B \rightleftharpoons \frac 3{2}A_2+\frac 1{2}B_2, K_2 \)
The relation between \(K_1\) and \(K_2\) is:
| 1. | \(K^2_1=2K_2\) | 2. | \(K_2= \dfrac { K_1 }{2}\) |
| 3. | \(K_1=\dfrac 1{\sqrt K_2}\) | 4. | \(K_2=\dfrac 1{\sqrt K_1}\) |
