**Problem (19): Equilibrium Constant Calculation for a Voltaic Cell**Consider the following redox reaction that occurs in a voltaic cell:\[ \text{Cr}^{2+} (\text{aq}) + \text{Cu}^{2+} (\text{aq}) \rightarrow \text{Cr}^{3+} (\text{aq}) + \text{Cu}^{+} (\text{aq}) \]**Question:** If the cell is operating at 25°C, what is the value of the equilibrium constant (K_eq)?**Options:**- (A) \( 1.41 \times 10^{11} \)- (B) \( 1.19 \times 10^{18} \)- (C) \( 5.53 \times 10^{5} \)- (D) \( 2.79 \times 10^{33} \)- (E) \( 1.81 \times 10^{-6} \)---This problem requires an understanding of redox reactions and the calculation of equilibrium constants in electrochemical cells. The equilibrium constant, \( K_{eq} \), varies based on the Gibbs free energy change (ΔG°) for the reaction, which is linked to the cell potential (E°cell) by the following relationship:\[ \Delta G° = -nFE°_{cell} \]Where:- \( \Delta G° \) is the standard Gibbs free energy change.- \( n \) is the number of moles of electrons transferred in the reaction.- \( F \) is the Faraday constant (\( 96,485 \, \text{C/mol} \)).- \( E°_{cell} \) is the standard cell potential.The relationship between the equilibrium constant \( K_{eq} \) and the Gibbs free energy is given by:\[ \Delta G° = -RT \ln(K_{eq}) \]Where:- \( R \) is the universal gas constant (\( 8.314 \, \text{J/mol·K} \)).- \( T \) is the temperature in Kelvin (\( 298 \, \text{K} \) for 25°C).These equations allow for calculating \( K_{eq} \) based on \( E°_{cell} \). However, direct calculation isn't demonstrated here, the options listed are potential values of \(
