Question

Arrange the following steps in the correct sequence to calculate the electrode potential of a polymer electrolyte system using the Nernst equation. \[ A.\ \text{Substitute value into the Nernst equation} \] \[ B.\ \text{Write the balanced electrode reaction} \] \[ C.\ \text{Identify the ionic species and their concentration in polymer electrolyte} \] \[ D.\ \text{Calculate the electrode potential under non-standard conditions} \] Choose the correct answer from the options given below:
• \( \mathrm{C \rightarrow B \rightarrow A \rightarrow D} \)
• \( \mathrm{B \rightarrow C \rightarrow A \rightarrow D} \)
• \( \mathrm{B \rightarrow A \rightarrow C \rightarrow D} \)
• \( \mathrm{A \rightarrow B \rightarrow C \rightarrow D} \)

• A. \( \mathrm{C \rightarrow B \rightarrow A \rightarrow D} \)
• B. \( \mathrm{B \rightarrow C \rightarrow A \rightarrow D} \)
• C. \( \mathrm{B \rightarrow A \rightarrow C \rightarrow D} \)
• D. \( \mathrm{A \rightarrow B \rightarrow C \rightarrow D} \)

Hint:

Always follow this sequence for Nernst equation problems:
• Write balanced reaction
• Identify ions and concentrations
• Substitute values
• Calculate electrode potential
