Bell-Evans-Polyani relationship

Bell-Evans-Polyani Relationship. The Bell-Evans-Polyani formula deals with the relationship between reaction rate and exothermicity for a series of related single-step reactions. Evans and Polyani pointed out that for a series of homolytic atom transfer reactions of the general type... [Pg.288]

Roberts and Steel investigated the applicability of an extended Bell-Evans-Polyani relationship to a series of hydrogen abstraction reactions. They developed a correlation equation that incorporated additional terms for electronegativity differences and for radical stabilization effects ... [Pg.1056]
