There are several factors that affect the rate
I Review Cons tants Penodic
constant 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 the rate constant can be
Part A
summarized in an equation called the Arrhenius
equation:
A certain reaction has an activation energy of 67.0 kJ/mol and a frequency factor of A1 = 3.20x1012
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.
