For the following reactions, predict whether the mole fraction of the reactants or products increases or remains the samewhen the volume of the reaction vessel is increased. a. 3: 20; ) + hzrg) = 2hbr(g)b. 20-14(3) ‘——‘ c2h2(g) + 31-12(3)c. 21-11(g) ‘——‘ 12(5) -i- h2(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.
