You can download Atkins’ Physical Chemistry 11th Edition by Peter Atkins, Julio de Paula and James Keeler free in pdf format.
Atkins’ Physical Chemistry is widely acknowledged by both students and instructors around the globe to be the textbook of choice for studying physical chemistry. The eleventh edition has been enhanced with additional learning features and math support, and reorganized into discrete Topics, to make the text more flexible for teachers and more readable for students.
“I like the division of the material into shorter ‘chapters.’ This helps to navigate through the material and break it up into ‘lecture-size’ bites. This is a comprehensive and well-organised textbook that covers all the core physical chemistry. It is attractively presented with excellent
online resources and makes a major effort to guide the student carefully through the more demanding mathematics and derivations.”
–Eleanor Campbell, Edinburgh University
“I really like the new approach. I like the checklist of concepts and the overarching ‘why you need to know this material’ pointers at the start of each chapter.”
–Darren Walsh, University of Nottingham
“I have used this book for more than 30 years. It is the best textbook of physical chemistry for year 2 and year 3 students in physical science departments, and for their teachers. I also use this textbook as a reference book for teaching other courses and even for my research.”
–Wuzong Zhou, St. Andrews University
