Question

Quizplus · Accepted Answer

To find the standard potential of the given cell, we need to subtract the standard potential of the anode from the standard potential of the cathode. From the given reaction, we can identify that Fe is the anode and Cu is the cathode.

Standard potential of the anode, Fe = -0.441 V (given)

Standard potential of the cathode, Cu = +0.340 V (given)

Standard potential of the cell, Cu|Cu2+ (1 M) || Fe2+ (1 M)|Fe = +0.340 - (-0.441) = +0.781 V

Therefore, the answer is D) 0.781.
