26. Which of the following statements is mathematically CORRECT for an operating electrochemical cel — Electrochemistry Chemistry Question

💡 Solution & Explanation

At chemical equilibrium, the net driving force for the reaction is zero ($\Delta G = 0$). Since $\Delta G = -nFE_{cell}$, the operating cell potential $E_{cell}$ strictly equals zero. The standard values ($E^\circ$ and $\Delta G^\circ$) are fixed constants and do not generally equal zero unless it is a concentration cell.
