Using 18 volts in the Faraday calculation leads to an inflated value because the relationship between voltage, energy, and charge is not linear. Faraday's law states that the amount of substance produced at an electrode is proportional to the charge passed, which is affected by the voltage applied. When higher voltage is used, the energy per charge increases, resulting in a larger calculated Faraday constant. This misunderstanding highlights the importance of maintaining consistent voltage levels in electrochemical experiments. Ultimately, using 18 volts instead of 9 volts distorts the expected results due to the direct correlation between voltage and energy calculations.
