Standard Potential Calculator

Calculate E° from thermodynamic data or combine half-reactions

Key Relationships

  • dG° = -nFE° - Links thermodynamics to electrochemistry
  • E° = (RT/nF)ln(K) - At 25°C: E° = (0.0592/n)log(K)
  • K = exp(nFE°/RT) - Equilibrium from potential
  • Positive E° = spontaneous reduction
