To determine the cell reactions and their (emfs), I need to know the specific type of cells or reactions involved. Different types of cells (such as galvanic cells, electrolytic cells, etc.) have different reactions and emfs.
Could you please provide more details about the type of cell or reaction you're referring to? For example, are you asking about a specific redox reaction in a galvanic cell, or perhaps a specific electrolytic process? This information will help provide a more accurate response for you. Thank you very much
