In the Deacon process, hydrogen chloride gas is oxidised by oxygen to produce chlorine gas and water vapour in a reversible reaction:
4HCl(g)+O2(g)⇌2Cl2(g)+2H2O(g) 4\text{HCl}(\text{g}) + \text{O}_2(\text{g}) \rightleftharpoons 2\text{Cl}_2(\text{g}) + 2\text{H}_2\text{O}(\text{g}) 4HCl(g)+O2(g)⇌2Cl2(g)+2H2O(g)Predict the effect that adding a copper(II) chloride catalyst has on the equilibrium yield of chlorine.
