The ideal course companion, Elements of Physical Chemistry is written specifically with the needs of undergraduate students in mind, and provides extensive mathematical and pedagogical support while remaining concise and accessible. For the seventh edition of this text, the material has been reorganized into short Topics, which are grouped into thematic Focus sections to make the text more digestible for students, and more flexible for lecturers to teach from. At the beginning of each topic, three questions are posed, emphasizing why it is important, what the key idea is, and what the student should already know.
