tional reading are supplied with each chapter. Six appendices covering 22 pages are concerned with units, an excellent table of the universal physical constants, various tables on electronic structure and properties of the elements, a discussion of electrical oscillations, eight pages on special relativity theory, and three pages on the elementary theory of radioactive decay.Errors are minor and generally of an insignificant nature at this embryonic stage of development of young scientists.The reviewer heartily recommends this book for the collegiate modern physics course.
The decomposition of oxalic acid vapor at 0.9 mm. pressure has been studied over the range 127-157'.The only products found are equimolar quantities of carbon dioxide and formic acid, and the kinetics of the decomposition are first order with respect to oxalic acid. The observed hrrhenius parameters are: E = 30.0 f 1.3 kcal. mole-', and log ( A , see. -I) == 11.9 =t 0.7. 'The LLlow-iiorinal" pre-exponential factor, modest activation energy, and tentative evidence for absence of a major free-radical component to the mechanism are viewed as supporting assumption of a uniniolecular mechanism via a cyclic activated complex. Comparison is made to results on the solution decomposition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
