Redox Reactions and Electrochemistry

Question 1

Spontaneous or not: electrolytic, galvanic, concentration cells

Answer 1

electrolytic = non-spontaneous
galvanic = spontaneous
concentration = spontaneous

Question 2

∆G for electrochemical cell

Answer 2

∆G = -nFE.cell
n = # moles e- exchanged
F = Faraday

Question 3

Nernst equation

Answer 3

E.cell = Eº.cell - (RT/nF) * lnQ
