RATE CONSTANT

[thubelihle]

Hi.
l am given a rate constant. k, at one temperature only. The simulation requires activation energy, E and pre-exponential factor, A, which are not provided in the paper. How do l calculate E and A with only one k at one temperature? if given k at two temperatures l would have used the Arrhenius equation, but l only have k at one temperature.

If you have the rate constant only for one temperature, you can simply not enter the Arrhenius term (which is ok as long as your reaction is performed on the temperature at which you know the rate constant).

Attached is the picture of the required simulation input. lt requires input of A and Ea and not k. Thanks

Which application is that?

lts DWSIM, learning COCO and DWSIM at the same time

I imagine there too you can set the activation energy to 0, which is the same as no Arrhenius term (as exp(0)=1).
