The Electron Tower
What will be an ideal response?
E0' reaction (reduction potential) = E0'acceptor - E0'donor
•Goal: pair stronger e- donor & stronger e- acceptor.
Glucose (donor) + 6O2 (acceptor) à 6CO2 + 6H2O
+820 - (-430) = 1250 mV
•DG0' = -nFE0'
-n = # electrons transferred, F = Faraday constant (96.5)
•+E value = -G value
•-482.5 = -4 96.5 1.25 V
