Thepreexponential factor AA is part of the Arrhenius equationwhich was formulated by the Swedish chemist Svante Arrhenius in1889 The preexponential factor is also known as the frequencyfactor and represents the frequency of collisions betweenreactant molecules Although often described as temperatureindependent it is actually dependent on temperature because it isrelated to molecular collision which is a function oftemperatureTemperature Dependence of ReactionsTheunits of the preexponential factor vary depending on the order ofthe reaction and thus on the rate constant In a first orderreaction the units of the preexponential factor are reciprocalseconds Because the preexponential factor depends on frequency ofcollisions its related to collision theory and transition statetheoryTheArrhenius equation introduces the relationships between rate andAA EaEa and TT where AA is the preexponential factor EaEa isthe activation energy and TT is the temperature Thepreexponential factor AA is a constant that See Answer
