Question 1

The industrial synthesis of phosgene (COCl2\text{COCl}_2COCl2​) from carbon monoxide and chlorine is a reversible reaction:

CO(g)+Cl2(g)⇌COCl2(g) \text{CO(g)} + \text{Cl}_2\text{(g)} \rightleftharpoons \text{COCl}_2\text{(g)} CO(g)+Cl2​(g)⇌COCl2​(g)

The process is typically carried out at a pressure of 5 atmospheres.

Explain the effect that a pressure lower than 5 atmospheres would have on:

a.

the rate of attainment of equilibrium

[2]
b.

the equilibrium yield of phosgene
