(a): $X \leftrightharpoons Z$

Work Step by Step

1. Calculate $K_c$ for the first and the second diagram, considering each chemical balanced equation; if they are equal, this is the correct equation. (a) $$K_{c1} = \frac{3}{6} = 0.5$$ $$K_{c2} = \frac{4}{8} = 0.5$$ Therefore, the correct answer is (a): $X \leftrightharpoons Z$
