How to Use This Calculator
  1. Enter cathode and anode reduction potentials (E°) in volts.
  2. Set temperature (K), electrons transferred (n), and product and reactant ion concentrations.
  3. Review standard cell potential, Nernst equation potential, and equilibrium constant.
  4. A positive cell potential indicates a spontaneous reaction under the given conditions.
