Tutorial Electrochemistry ORR_thermo

[imondal8007]

Hello,

I am wondering why there are gaseous products in the electrochemistry tutorial and how the pressures of each gaseous species (O2_g, H2O_g, H2O2_g and Pe_g) in the species definition of the ORR_thermo tutorial are determined? I am also confused about the fact that if we change the pressure of Pe_g, does it change the pH condition?

Thank you.
