Chemistry / Unit 11 Chem 2190 short lesson, about 20 seconds
E°cell, ΔG°, and K as One Fact
Captions available
The idea
E°cell, ΔG°, and K describe one reaction's spontaneity from three connected angles; any one determines the other two through ΔG° = −nFE°cell and ΔG° = −RT ln K.
In practice
A large positive E°cell implies a large negative ΔG°, which implies a large K favoring products.
Where people slip
Treating these as three facts to memorize, not one relationship viewed three ways, misses the point.
