Distillation Part 17: Enthalpy Concentration Diagram

[@gyocharou4737]

hi, great video! thank u for the explanation. i have a question on HG calculation bc im still confused, do we use the heat capacity of vapor or liquid? they teach me to use vapor heat capacity here but i feel like it isnt right after watching this video

@@gyocharou4737 In this case these are heat capacities of pure liquid A and Liquid B. Because in order to create the Vapor phase, the liquid solution has to be heated to the dew point by supplying sensible heat and then the latent heat will be supplied to change the phase from liquid to Vapor.
