Re: Final Exam points
Following up on on the mention about the points for posting on Chemistry Community, does anyone know if posting twice one week could replace the point of another week of not posting? I wasn't able to post last week bc I didn't have Wi-Fi at home and my phone wasn't working. thanks in advance!

Pre-Equilibrium Approach
Hey all! Can someone explain to me how I am supposed to know when to use this approach? I understand that the main aspect hinting towards using it is when the intermediate is being used up initially, but how do we assume that? Is it mentioned in the question? Thanks in advance.
