Time constants During Galvanostatic Transients and Faradaic Efficiency

2 Time Constants During Galvanostatic Transients and Faradaic Efficiency 

The faradaic efficiency, A, can be computed in every NEMCA experiment from its definition, i.e.  

Thus by simply measuring tD, rj and NG one can estimate A. The thus computed values are always in excellent qualitative agreement with those accurately computed from Eq. (4.19). The interested reader can check this with all galvanostatic transients presented in this book. 

Another use of Eq. (5.3) is that by measuring tD and and computing A via Eq. (4.19) one can estimate the catalyst surface area NG. Alternatively this also can be done by comparing the parameter 2FNG/I with the experimentally measured time constant t via Eq. (4.32).
