For a closed circuit Daniell cell, which of the following plots is the accurate one at a given temperature?

### Core Logic For a closed circuit Daniell cell operating under given conditions, standard cell potential E_textcell^circ$E_{\text{cell}}^{\circ}$ remains constant with time during discharge until equilibrium or noticeable concentration shifts occur in a specific manner, or cell potential versus time plots reflect constancy of standard electromotive force terms before polarization effects take over. ### Step 1: Final Conclusion Plot 2 accurately depicts the expected trend where E_textcell^circ$E_{\text{cell}}^{\circ}$ remains constant with time. ### Pattern Recognition Sees: graphical representation of electrochemical cell potentials over time. Trap: Confusing standard cell potential E^circ$E^{\circ}$ with operating cell potential E_textcell$E_{\text{cell}}$. ### Chapter Mix Class 12 Chemistry: Electrochemistry
