Vedclass · Answer

(D) According to Le Chatelier's principle,adding $SO_2$ (a product of the first equilibrium) will shift the first equilibrium $SO_2Cl_{2(g)} \rightleftharpoons SO_{2(g)} + Cl_{2(g)}$ to the left. This results in a decrease in the concentration of $Cl_2$. The second equilibrium is $CO_{(g)} + Cl_{2(g)} \rightleftharpoons COCl_{2(g)}$. Since the concentration of $Cl_2$ decreases,the second equilibrium will shift to the left to compensate for the loss of $Cl_2$. As a result,$COCl_2$ will decompose,leading to an increase in the amount of $CO$ and $Cl_2$. Therefore,the amount of $CO$ will increase.

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?
