delta G=-nFE

[205389184]

If the n in DeltaG=-nFE is not explicitly given, how do we calculate its value?

[Andrew Pfeiffer 2E]

We can calculate it if we have all the other components of this equation (the standard change in Gibbs free energy, the energy, and Faraday's constant). Otherwise, we must use additional equations and knowledge about the conditions to indirectly solve for n and plug it back in.

[Jasmine Vallarta 2L]

you can try to find the half rxns

[Ritu Gaikwad 2E]

If the n is not given, look at the half reactions and find the number of moles of electrons transferred and that is your n value because that is what n stands for in the equation.

[Shimei_2F]

You can find it by balancing the electrons of the half-reactions and that's the n, the amount in moles of electrons that were transferred.

[saigorijavolu2k]

You balance the half reactions and find out how many electrons are transferred.

[Tahlia Mullins]

If n is not given, you can go through the process of balancing the half reactions for oxidation and reduction, eventually finding the number of moles of electrons being transferred!

[AronCainBayot2K]

You can calculate n whether by the other information given, such as Gibbs Free Energy, or using the half reactions to determine the amount of electrons.
