Question
Calculate the rate constant, ?, for a reaction at 69.0°C that has an activation energy of 81.5 kJ/mol and a frequency factor of 5.23×10 11 s−1.
k= _____________
(Answer in J not Kj)
Expert Solution
Required Formula
According to activated transition state theory, the rate of a reaction is given by the Arrhenius equation:
Where k=rate constant
A=Pre-exponential factor or frequency factor
Ea=Activation energy
R=Universal gas constant =8.314 JK-1mol-1
T=temperature in kelvin (K)
