We are going to ask questions for the following reaction according to Le Chatlier's Principle. I will start with a question, the next person should answer it and ask their own question. You can add numbers to the question, but let's try to keep it fairly conceptual.

                                        CaCO₃(s) ⇌  CaO(s)  +  CO₂(g)                 ∆H = 131.4 kJ

Explain what happens to the value of the equilibrium constant when CaO is added to the reaction at equilibrium.

The following link is to Chemistry Crash Course #28 on Equilibrium. It is a 10 minute video.
After you have watched it, comment on a concept that you learned more about, something that you found confusing/incorrect, or perhaps something that you think explains one of the concepts in a better/different way. Just one of these, don't get carried away! (By the way, you might learn something from #29 also)
