תקציר	Substitution reaction kinetics analysis is the systematic study of how fast nucleophiles replace leaving groups in organic and inorganic compounds. Formalized by Edward Hughes and Christopher Ingold in the 1930s, this framework distinguishes between bimolecular (SN2) and unimolecular (SN1) mechanisms, connecting mechanism to reaction rates, and enabling prediction of reactivity based on substrate structure, nucleophile strength, and solvent effects.	Redox reaction mechanism analysis is the systematic study of electron transfer pathways in oxidation-reduction reactions. Formalized by Rudolph Marcus in the 1950s (earning him the Nobel Prize in 1992), this framework explains how electrons move between reactants, what factors control reaction rates, and how electronic and geometric factors influence the ease of electron transfer.
