Data Source and Methodology
All calculations are strictly based on the Nernst Equation as defined in electrochemistry literature. Refer to authoritative sources like scientific papers and textbooks for more details.
The Formula Explained
E = E° - (RT/nF) ln(Q)
Glossary of Terms
- E°: Standard Electrode Potential.
- T: Temperature in Kelvin.
- Q: Reaction Quotient (Ion Concentration Ratio).
- E: Cell Potential.
How It Works: A Step-by-Step Example
Assume a standard potential E° of 1.1 V, temperature of 298 K, and a concentration ratio Q of 10. The Nernst Equation gives you the cell potential E by substituting these values into the formula.
