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)
