Question

Delta G = -nFE (How do you find n when different number of electrons)

One reaction transfers 3e, and the other 2e, Would n be -6?

Answer 1

3 Fe2+ + 6 e− + 2 NO + 4 H2O → 3 Fe(s) + 2 NO−3 + 8 H+ + 6 e−
Withdraw the electrons.

ΔrG=−vFEcell

where:

Ecell=Er−El

r and l is a subscript for right and left.

n=no. of moles of products_no. of moles of reactants
