Chapter 29. The Electric Potential
... If 2H+O=>H2O released E=1 eV of “chemical energy,” what is the total energy release in joules and how high would that lift one kg subject to earth gravity? The number of molecules formed = the number of protons in one gm = the inverse of the proton mass (1.67e-24 gm) = Avogadro’s number N=6e23. The ...

In Figure 2a and b, τ has been color-coded from blue for a very large desorption time constant (1010 s), to magenta for sufficiently small τ (10−4 s). A linear trend is obtained over the full range of potential (current) for extreme values of τ ...
