The correct Answer is:
To find the equilibrium constant \( K_c \) for the cell reaction, we can use the Nernst equation and the relationship between the standard cell potential \( E^\circ_{cell} \) and the equilibrium constant \( K_c \). ### Step-by-Step Solution: 1. **Identify the Given Values**: - Standard cell potential, \( E^\circ_{cell} = 0.59 \, V \) - Number of electrons transferred, \( N = 1 \) (since the cell involves one electron) - At 298 K, \( \frac{2.303RT}{F} = 0.059 \, V \) 2. **Use the Nernst Equation**: The Nernst equation at equilibrium can be simplified to: \[ E^\circ_{cell} = \frac{0.059}{N} \log K_c \] Since we are at equilibrium, \( E_{cell} = 0 \). 3. **Substitute the Known Values**: Substitute \( E^\circ_{cell} \) and \( N \) into the equation: \[ 0.59 = \frac{0.059}{1} \log K_c \] 4. **Rearranging the Equation**: Rearranging gives: \[ \log K_c = \frac{0.59}{0.059} \] 5. **Calculate the Logarithm**: Now calculate \( \frac{0.59}{0.059} \): \[ \log K_c = 10 \] 6. **Find \( K_c \) from the Logarithm**: To find \( K_c \), we take the antilogarithm: \[ K_c = 10^{10} \] 7. **Final Answer**: Therefore, the equilibrium constant \( K_c \) for the cell reaction is: \[ K_c = 10^{10} \]
