Hydrogen chloride and oxygen react to form water and chlorine, like this: 4HCl(g)+O2(g)2H2O(g)+2Cl2(g) Suppose a mixture of HCl,O2,H2O and Cl2 has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left
