My reactant is only 1 mol% of the total flow rate, so I was wondering if you account for only the reactant flow rate when calculating for the theoretical calculation?
I am following the supplementary information for "Stable and Selective Electrochemical Reduction of Carbon Dioxide to
Ethylene on Copper Mesocrystals" as a reference to calculate the faradaic efficiency.

The Faraday efficiency n of a gaseous product j is determined by means of
n = z*F*xj*Fm / I
where F is Faraday’s constant, z is the number of electrons exchanged, xj is the mole fraction of the gas j in the gaseous mixture analyzed, Fm is the molar flow rate, and I the total current.
Hi Karim,
Thank you for your response. Does this mean that I should use the molar flow rate of my reactant or the total molar flow rate?
