Reduction potentials for exam 2 Flashcards
1
Q
If given the reduction potentials for two half reactions: which half reaction is the electron donor?
A
the one that is negative ENP, reductant
2
Q
Which is the electron acceptor?
A
the one that is positive, oxidant
3
Q
Which half rxn is the reductant?
A
the negative one
4
Q
Which half rxn is the oxidant?
A
the positive one
5
Q
Which half reaction is oxidized?
A
the reductant, the negaitv one
6
Q
What is the equation for change in reduction potential?
A
delta Enp= Enp acceptor - Enp donor
DO NOT flip signs even if you flip products and reactants.
DO NOT multiply by a coefficient even if you have to add coefficients to balance equations.
