Question 5

Carbon dioxide reacts with hot carbon in a closed reactor. The reaction reaches equilibrium. The forward reaction is endothermic.

CO2(g)+C(s)⇌2CO(g)\text{CO}_2\text{(g)} + \text{C(s)} \rightleftharpoons 2\text{CO(g)}CO2​(g)+C(s)⇌2CO(g)

a.

Explain why decreasing the temperature lowers the equilibrium yield of carbon monoxide.

b.

Explain why increasing the pressure lowers the equilibrium yield of carbon monoxide.
