|Temperature (K)||Rate Constant (1/s)|
Use an Arrhenius plot to determine the activation barrier for the reaction.
We’re being asked to determine the activation energy (Ea) of a reaction given the temperature and rate constant values.
We’re given the temperature (K) and rate constant (1/s) values.
This means that we need to use the two-point form of the Arrhenius Equation:
k = rate constant
Ea = activation energy (in J/mol)
R = gas constant (8.314 J/mol • K)
T = temperature (in K)
A = Arrhenius constant or frequency factor
