This the course page for Chemical Thermodynamics, taught by Prof. Pratyush Tiwary in Fall 2023. Relevant links, references etc. will be uploaded here. I will also upload homework/exam problems here (but likely not their solutions except those for midterms and final exam). The class will taught live in-person, with recorded videos through youtube available after class. However you should try to attend the class and engage in discussions if you want full participation points (see syllabus for details).
Final will happen as per dates announced by university - Wednesday Dec 13, 0800-1000 in CHM2201. It will be in-class, closed book, closed notes, closed internet, with 2-sided 1-page cheat sheet allowed.
