### Chemical Equilibrium Constants

The table presents a series of chemical reactions, along with their respective equilibrium constants (Log K), standard electrode potentials (pe°), and reduction potentials (E° in mV). These values are critical in understanding the behavior of reactions in various conditions and can be used to predict reaction spontaneity and direction.

#### Key

- **Reaction**: Represents the chemical equation for the transformation being studied.
- **Log K**: The logarithm of the equilibrium constant, providing insights into the favorability of a reaction at standard conditions.
- **pe°**: The standard electron potential, indicating the tendency of a substance to gain or lose electrons.
- **E° (mV)**: The standard reduction potential in millivolts, which also provides similar information to pe°.
