Hemoglobin scenario
In this movie, we describe the hemoglobin scenario from the perspective of comparing Q (a measure of the current state of a reaction) to K (a measure of the equilibrium state of a reaction).
We recommend you (i) watch the following movie on the Hemoglobin story (ii) go through the library items used in this movie, and (iii) watch the Hemoglobin story again. Note that since the Hemoglobin story uses ideas covered in the library items, the first time you hear the story you will not yet have the background information needed to understand it in detail.
