FREE Expert Solution

We’re being asked to determine what happens as you increase the temperature to the reaction rate and activation energy.



We need to use the two-point form of the Arrhenius Equation:


 k=Ae-EaRT  


where: 

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
