sci.Nernst-equation-cell-potential Calculator
Calculates cell potential at non-standard conditions: E_cell = E°cell − (RT/nF)ln Q, and equilibrium concentration from E_cell = 0. At 25 °C, E = E° − (0.0592/n)log Q — a concentration cell (same electrodes, different concentrations) has E° = 0 and operates purely from concentration gradient.
Inputs
E0 V
Reference formula or conversion factor shown for context.
N Electrons
Reference formula or conversion factor shown for context.
T K
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Q React
Reference formula or conversion factor shown for context.
