I'm having trouble finding a posted literature value for the activation energy for the Daniell cell redox reaction:

$$\ce{Cu^2+ + Zn -> Cu + Zn^2+}$$

Where might I be able to find this information?

  • $\begingroup$ Electron transfer is extremely fast, that finding its rate constant is not a trivial exercise. $\endgroup$ – M. Farooq Feb 12 at 1:10
  • $\begingroup$ The equation is the summary of 2 processes ongoing on 2 different places, while activation energy applies on a single elementary reaction step. $\endgroup$ – Poutnik Feb 12 at 4:41
  • $\begingroup$ An activation energy has a sense in a homogeneous mixture. This is not the case in a Daniell cell $\endgroup$ – Maurice Feb 12 at 8:51
  • $\begingroup$ @Maurice, "An activation energy has a sense in a homogeneous mixture. This is not the case in a Daniell cell" is a misconception. Electrode kinetics is very vast field and people do report activation energy, see e.g., pubs.acs.org/doi/abs/10.1021/jp9721309 $\endgroup$ – M. Farooq Feb 12 at 13:47
