Equilibria — practice question

The following two reactions are given. reaction 1: $\text{X}_2(g) + \text{Y}_2(g) \rightleftharpoons 2\text{XY}(g)$ reaction 2: $\text{XY}(g) \rightleftharpoons \frac{1}{2}\text{X}_2(g) + \frac{1}{2}\text{Y}_2(g)$ For reaction 1, the equilibrium constant, $K_p$, is $0.0052$. What is $K_p$ for reaction 2?
