**Equilibrium Constant Expression Selection**

For the reaction depicted in the diagram, choose the correct equilibrium constant expression. In the diagram, X atoms are represented in orange, and Y atoms in blue.

**Chemical Reaction:**

\[ \text{X}_2(g) + \text{Y}_2(g) \rightleftharpoons 2\text{XY}(g) \]

**Diagram Description:**

The image shows an "Equilibrium mixture" with spheres of two colors: orange (X atoms) and blue (Y atoms) representing different atoms in a container. This illustrates the chemical reaction at equilibrium.

**Options for Equilibrium Constant (\(K_c\)):**

1. \(K_c = \frac{{[\text{XY}]^2}}{{[\text{X}_2][\text{Y}_2]}}\)
2. \(K_c = \frac{{2[\text{XY}]}}{{[\text{X}_2][\text{Y}_2]}}\)
3. \(K_c = \frac{{[\text{X}_2][\text{Y}_2]}}{{[\text{XY}]}}\)
4. \(K_c = \frac{{[\text{X}][\text{Y}]}}{{[\text{XY}]^2}}\)

Select the expression that correctly represents the equilibrium constant for this reaction.
