In which of the following ways are the processes that occur in electrolytic cells the opposite of those occuring in galvanic cells? a. In electrolytic cells, chemical energy is produced from electrical energy.
b. In galvanic cells, the converse is true. Electrolytic cells contain nonspontaneous reactions, while the reactions in galvanic cells are spontaneous.
c. In electrolytic cells, reduction occurs at the anode rather than at the cathode (as it does in galvanic cells).
d. In electrolytic cells, the cathode is negatively charged, while the anode is positively charged (the reverse is true for galvanic cells)
