100%
The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins
and is typically written as
k= Ae /T
• Part A
where Ris the gas constant (8.314 J/mol - K), A is a constant called the frequency factor, and Ea is the
activation energy for the reaction.
The activation energy of a certain reaction is 39.2 kJ/mol. At 20 °C , the rate constant is 0.0130s. At what temperature in degrees Celsius would this reaction go twice as fast?
However, a more practical form of this equation is
Express your answer with the appropriate units.

where ki and k2 are the rate constants for a single reaction at two different absolute temperatures (T and
T2).
T = 4.39
