Cohen, Richard W.; Whitmer, John C. – Journal of Chemical Education, 1981
Describes how Gibbs valley graphs can clarify the relation between the Gibbs function and chemical equilibrium. Gives examples from gas phase equilibria. (CS)
Descriptors: Chemical Equilibrium, Chemical Reactions, Chemistry, College Science
Peer reviewed Peer reviewed
Murdoch, Joseph R. – Journal of Chemical Education, 1981
Presents information concerning a fundamental concept for understanding reaction rate, the idea of a rate-limiting step for a chemical reaction. Discusses problems in using flow analogies and introduces an alternative approach to finding the rate-limiting step based on locating the transition state of highest energy. (CS)

Coller, B. A. W.; And Others – Journal of Chemical Education, 1980
Analyzed are the deficiencies of a traditional freshman course in chemistry, including (1) chemistry model usage, (2) inadequate discrimination between related but different basic concepts, and (3) methods for teaching elementary ideas. Described is an approach used to resolve these problems. (CS)
Descriptors: Chemistry, College Science, Higher Education, Instructional Innovation
Peer reviewed Peer reviewed
Adamson, Ishola – Journal of Chemical Education, 1980
Described is the first part of a two-term project involving final-year students in biochemistry. Listed are the required experiments compiled to test students' abilities to search biochemical literature, extract experiments from journals and carry them out, generate data, and interpret results. (CS)

Feliu, Anthony L. – Journal of Chemical Education, 1990
Discussed are the properties, chemistry, generation of precursors, and use in organic synthesis of this isotope of carbon. The use of carbon-11 in research is emphasized. Pitfalls and possibilities are described. (CW)
Descriptors: Chemical Analysis, Chemical Reactions, Chemistry, College Science
Peer reviewed Peer reviewed
Logan, S. R. – Journal of Chemical Education, 1990
Discussed are the kinetic interactions of these chemical processes and the determination of the actual order of such reactions. Included are multiple exchange, catalytic exchange with deuterium, and depletion of the original substrate. (CW)
Descriptors: Chemical Analysis, Chemical Reactions, Chemistry, College Science
Peer reviewed Peer reviewed
MacDonald, J. J. – Journal of Chemical Education, 1990
Suggestions for the use of two different conventions in difference and rate terms in thermodynamics are made. It is shown how this approach lends itself to an accurate and concise discussion of function changes for a chemical reaction. (CW)
