If you solve a Laidler problem using the methodology from Vallance, you have effectively created a “better” solution than the original manual.

Conversely, those who use (or create) better solutions:

Unlike introductory chemistry textbooks, Laidler's Chemical Kinetics does not have a widely circulated, publisher-produced "student solutions manual" that covers every single problem. Most PDFs found online are usually:

Detailed coverage of composite reactions, including gas-phase and solution kinetics.

If you require a modern textbook that includes a dedicated, easily accessible solutions manual, consider these alternatives:
