Vedclass · Answer

(C) According to Le Chatelier's principle,an increase in temperature favors the endothermic direction of a reaction.
Reaction $(a)$ is the water-gas shift reaction,which is exothermic $(\Delta H < 0)$.
Reaction $(b)$ is the contact process step,which is exothermic $(\Delta H < 0)$.
Reaction $(c)$ represents the thermal decomposition of water,which is highly endothermic $(\Delta H > 0)$.
Reaction $(d)$ is the Deacon process,which is exothermic $(\Delta H < 0)$.
Therefore,only reaction $(c)$ will shift to the right side upon increasing the temperature.

Which of the following equilibria will shift to the right side on increasing the temperature?
