The supply of oxygen to tissues by blood can be explained by:

In a vessel,the following two systems are in simultaneous equilibrium: $PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$ and $COCl_{2(g)} \rightleftharpoons CO_{(g)} + Cl_{2(g)}$. If some $CO$ is added to the vessel at constant volume,then at the new equilibrium:

For the balanced reaction $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) + \text{Heat}$,which of the following conditions will favor the forward reaction?

What happens when a saturated solution of $CO_2$ is heated?

In the following system,$PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$ at equilibrium,upon addition of xenon gas at constant $T$ & $p$,the concentration of

For the formation of $NH_{3(g)}$ from $H_{2(g)}$ and $N_{2(g)}$,which one of the following graphs represents the yield of ammonia at equilibrium? (Assume $T_1 < T_2$,unless mentioned)
