Physical Chemistry is an Android application developed by RK Technologies, available for free under the Education & Reference category. The app provides a comprehensive guide to the subject, offering a detailed explanation of the concepts and guidance required to master the subject. Divided into three parts, it covers topics ranging from the properties of gases to quantum theory and molecular spectroscopy.

Part 1 of the app focuses on the discussion of equilibria in chemistry, including physical and chemical changes, and enthalpy and entropy. The chapters in this part deal with the bulk properties of matter. Part 2 covers contemporary techniques of materials science, including Nano-science and spectroscopy, and computational chemistry. Part 3 emphasizes the importance of kinetics of complex reactions and surface processes, and includes descriptions of polymerization, photochemistry, and enzyme- and surface-catalyzed reactions.

The app also includes a checklist of key equations, discussion questions, exercises, and problems to help users test their knowledge and understanding of the subject matter. With its comprehensive coverage and user-friendly features, Physical Chemistry is an excellent resource for students and professionals alike.
