The Nernst Equation Calculator determines the cell potential of an electrochemical cell under non-standard conditions using the Nernst equation E = E° − (RT/nF) × ln(Q), where E° is the standard cell potential, R is the gas constant, T is the temperature in Kelvin, n is the number of electrons transferred, F is the Faraday constant, and Q is the reaction quotient. This calculator helps understand how concentration, temperature, and reaction conditions affect the voltage of electrochemical cells. It is an essential tool for students, chemists, and electrochemistry researchers to analyze cell efficiency and predict reaction behavior in real-world conditions.
