For an electrolytic cell,
A)E is negative and ΔG is negative for the cell reaction.
B)E is negative and ΔG is positive for the cell reaction.
C)E is positive and ΔG is negative for the cell reaction.
D)E is zero and ΔG is positive for the cell reaction.

Question

Quizplus · Accepted Answer

For an electrolytic cell, E is negative because the cell reaction is nonspontaneous and needs an external energy source to proceed. ΔG is positive because work is required to force the reaction to occur against its natural direction. Therefore, the correct choice is B where E is negative and ΔG is positive.
