7.5 Magnitude of the Equilibrium Constant
The equilibrium constants for three hypothetical reactions at \(298\text{ K}\) are given in the table below.
Which of the following correctly ranks the reactions in order of greatest tendency to form products to least tendency to form products at \(298\text{ K}\)?
| Reaction | Chemical equation | \(K_{eq}\) |
|---|---|---|
| 1 | \(\text{A}(g) \rightleftharpoons \text{B}(g)\) | \(4.5 \times 10^{4}\) |
| 2 | \(\text{X}(g) \rightleftharpoons \text{Y}(g)\) | \(1.2 \times 10^{-1}\) |
| 3 | \(\text{M}(g) \rightleftharpoons \text{N}(g)\) | \(6.8 \times 10^{-8}\) |
Which of the following correctly ranks the reactions in order of greatest tendency to form products to least tendency to form products at \(298\text{ K}\)?
