a question about chemical equilibrium?

Question

CaCO3(s)+energy<->CaO(s)+CO2(g)
What direction would the equilibrium shift if CO2 is removed from the container?

Answer 1

If CO2 gas was to be removed from the container, it would invariably shift the equilibrium the way it was written - toward the
product or the right side of the equation. This happens because of a concept known as Le Chatelliers Principle. This is simply a manipulation (taking out CO2) to drive the equilibrium to favor producing calcium oxide. Below is the definition of Le Cha... Hope this all helps.

Answer 2

This is an application of LeChatlier's Principle. If you have an equilibrium and disturb it, the reaction will shift to minimize the disturbance.

In your example, if you remove CO2, the equilibrium will shift so that CO2 is replaced. So the equilibrium will shift to the right to make more CO2.

The LeChatlier Principle is a very important and useful idea when dealing with equilibria. Work to understand it..
