Hey everyone, I need help with this question: 1. The problem statement, all variables and given/known data 2-pentanone is an important industrial intermediate. When using the pure liquid as the reference state, in which solvents (examples and explanations) would you expect it to have an activity of a) less than one, b) one, and c) greater than one? 3. The attempt at a solution I feel like it must be a pretty simple question if I knew how activity was related to intermolecular forces- but I don't! Can anyone enlighten me on that? Thanks!
