At 100 ∘c the equilibrium constant for the reaction cocl2(g)←→co(g)+cl2(g) has the value kc=2.19×10−10. are the following mixtures of cocl2, co, and cl2 at 100 ∘c at equilibrium? if not, indicate the direction that the reaction must proceed to achieve equilibrium.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
