On heating a mixture of $SO_2Cl_2$ and $CO$,two equilibria are simultaneously established: $SO_2Cl_{2(g)} \rightleftharpoons SO_{2(g)} + Cl_{2(g)}$ and $CO_{(g)} + Cl_{2(g)} \rightleftharpoons COCl_{2(g)}$. On adding more $SO_2$ at equilibrium,what will happen?

The reaction $2SO_{2(g)} + O_{2(g)} \rightleftharpoons 2SO_{3(g)} + q$ is favored by:
