Hansen, David E.; Raines, Ronald T. – Journal of Chemical Education, 1990
Discussed is the fundamental role that the favorable free energy of binding of the rate-determining transition state plays in catalysis. The principle that all of the catalytic factors discussed are realized by the use of this binding energy is reviewed. (CW)

Smith, Derek W. – Journal of Chemical Education, 1990
Presented is a modification of Bratsch's prescription so that difficult problems are obviated while simple, familiar Pauling electronegativities are retained. Discussed are the equilibration of electronegativity in molecules, group electronegativities, coordination compounds and molecules with dative bonds, ions, and correlation with core…
