The following reaction takes place in a cell at 298 K: $2M^{3+}(aq) + 2I^{-}(aq) \rightarrow 2M^{2+}(aq) + I_2(s)$. What is the value of $\log K_c$ for this reaction? (Given: $E_{cell}^\circ = 0.235 V, F = 96500 C mol^{-1}, R = 8.3 J mol^{-1} K^{-1}$)

The emf values of three galvanic cells I, II and III are \(E_1\), \(E_2\) and \(E_3\) respectively. Determine the correct order among them. \[ \text{(I)}\quad Zn|Zn^{2+}(1M)||Cu^{2+}(0.1M)|Cu \] \[ \text{(II)}\quad Zn|Zn^{2+}(1M)||Cu^{2+}(1M)|Cu \] \[ \text{(III)}\quad Zn|Zn^{2+}(0.1M)||Cu^{2+}(1M)|Cu \]
