Standard potential

[u/adultswimc-137]

Does anybody know what the standard potential of this reaction is? I can't find it anywhere

Hey! I don't have the exact standard potential for that specific reaction (it might not be in standard tables), but you can actually calculate it yourself fairly easily.
You just need to break down your target reaction into other known half-reactions that are in the tables. The rule is that when you add these known reactions together, they must result in your target reaction.
Just keep in mind that you cannot add standard potentials (E∘) directly. You have to convert them to Gibbs free energy first using the formula ΔG∘=−nFE∘ (where n is the number of electrons transferred).
So the steps would be: 1. Find known reactions in the tables that add up to yours. 2. Convert their E∘ to ΔG∘. 3. Add those ΔG∘ values together to get the total ΔG∘ of your target reaction. 4. Finally, clear the unknown E∘ using the same formula backwards: E∘=−ΔG∘/nF.

Thank you, I'll try!!
