内容説明・目次
内容説明
This textbook introduces chemistry and chemical engineering students to molecular descriptions of thermodynamics, chemical systems, and biomolecules.
Equips students with the ability to apply the method to their own systems, as today's research is microscopic and molecular and articles are written in that language
Provides ample illustrations and tables to describe rather difficult concepts
Makes use of plots (charts) to help students understand the mathematics necessary for the contents
Includes practice problems and answers
