Chemical Kinetics & CatalysisPre-exponential Factor
The constant A in the Arrhenius equation, representing the frequency of appropriately oriented collisions.
Chemical Kinetics & CatalysisPromoter
A substance that has little catalytic activity itself but greatly increases the effectiveness of a catalyst.
Chemical Kinetics & CatalysisPseudo-First-Order Reaction
A higher-order reaction that behaves as first order because one reactant is present in such large excess that its concentration is…
