Redox Reactions and Electrochemistry: JEE Main 2026 Chemistry question

One half cell in a voltaic cell is constructed by dipping silver rod in $\mathrm{AgNO_3}$ solution of unknown concentration, other half cell is Zn rod dipped in 1 molar solution of $\mathrm{ZnSO_4}$. A voltage of 1.60 V is measured at 298 K for this cell. What is the concentration of $\mathrm{Ag^+}$ ions used in terms of $\log x$ ($x=[\mathrm{Ag^+}]$) ? $E^\ominus_{\mathrm{Zn^{2+}/Zn}}=-0.76$ V, $E^\ominus_{\mathrm{Ag^+/Ag}}=+0.80$ V, $\frac{2.303RT}{F}=0.059$ V
