How can i calculate the amount of hydrogen generated and needed per volt & watt of an electrolysis device for hydrogenation?
Accepted Answer
The amount of hydrogen generated or needed per volt and watt of an electrolysis device for hydrogenation can be calculated using Faraday's law of electrolysis. Faraday's law states that the amount of substance deposited or evolved at an electrode during electrolysis is directly proportional to the amount of charge passed through the electrode. The amount of charge passed through the electrode is determined by the current and the time of electrolysis. The current is measured in amperes (A) and the time is measured in seconds (s). The amount of charge is calculated by multiplying the current by the time. The amount of hydrogen generated or needed can be calculated using the following equation:
m = zIt / M
where:
* m is the mass of hydrogen generated or needed in grams
* I is the current in amperes
* t is the time of electrolysis in seconds
* z is the number of electrons transferred per molecule of hydrogen (2 for hydrogenation)
* M is the molar mass of hydrogen (1.008 g/mol)
