The concepts introduced here are covered in High School and College chemistry courses and the misconceptions mentioned are quite common. With a well-led class discussion this activity does a good job modeling the the two concepts outlined by the author - equilibrium and limiting factors in reactions. I think additional examples for limiting factors are necessary in addition to the one provided to be sure the concept is well-developed and all misconceptions overcome but just reading this article and picturing the scene as this activity takes place provided a vivid picture of the movements at the particle level for both types of reactions. Very clever!
