Part A There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation called the Arrhenius equation: A certain reaction has an activation energy of 64.0 kJ mol and a frequency factor of Aj = 7.40x1012 k = Ae E/RT Express your answer with the appropriate units.
