Question

In what direction the following equilibrium will be shifted if some chlorine (Cl) gas is

introduced into the system at equilibrium ?
COCl2 (g) = CO + Cl2​

Answer 1

Answer:

When CO is added to the above system, the second reaction will go backwards in accordance with Le Chatelier's principle and hence, the concentration of the common molecule, i.e., Cl

2

Explain:

So, to counteract the decreased concentration of chlorine, first equilibrium will go forward and hence, the concentration of PCl

5

will decreased
