There are several factors that affect the rate
constant of a reaction. These factors include
I Review | Constants | Periodic Tab
temperature, activation energy, steric factors
(orientation), and also collision frequency, which
changes with concentration and phase. All the
factors that affect the rate constant can be
summarized in an equation called the Arrhenius
equation:
Part A
A certain reaction has an activation energy of 67.0 kJ/mol and a frequency factor of A1 = 3.20×1012
M-'s. What is the rate constant, k, of this reaction at 20.0 °C ?
k = Ae-E/RT
where k is the rate constant, A is the frequency
factor, E, is the activation energy,
R = 8.314 J/(mol K) is the universal gas
constant, and T is the absolute temperature.
Express your answer with the appropriate units. Indicate the multiplication of units explicitly either
with a multiplication dot (asterisk) or a dash.
