A battery's voltage depends on concentrations, not just chemistry. The Nernst equation E = E° − (RT/nF)·lnQ shows the cell voltage sliding as reactants are consumed — and reaching zero when the reaction hits equilibrium. Educational tool.

Governing equation

E = E^{\circ} - \frac{R T}{n F} ln Q = 1.1 - \frac{( 8.314 ) ( 298 )}{( 2 ) ( 96485 )} ln (1) = 1.100 V

Reading this result: At Q ≈ 1 the log term nearly vanishes, so the cell sits close to its standard EMF of 1.10 V.
