Which equation represents a change that results in an increase in disorder? 2Na(s) + Cl2(g) + 2NaCl(s)
CO2(g) → CO2 (s)
2H2(g) + O2(g) → 2H2O(l)
12(s) 12(g)

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
