Question

In each of the following questions, identify which way (to the left or to the right) does equilibrium shift to relieve the described applied stress:

5) Consider the following reversible reaction at equilibrium: CO(g) + Cl2(g) ⇌ COCl2(g). If chlorine gas is added to the equilibrium system, how is the stress relieved?

Answer 1

The equilibrium will shift to the right to relieve the stress caused by the increase in chlorine gas. This will result in the formation of more COCl2 gas and the consumption of CO gas.
