We’re being asked to determine which of the given statements apply to a voltaic cell.

Recall that a voltaic or galvanic cell is an electrochemical cell that is spontaneous and produces electricity. On the other hand, an electrolytic cell is nonspontaneous.

Recall that if:

• ΔG < 0 or ΔG = (–); the reaction is spontaneous

• ΔG > 0 or ΔG = (+); the reaction is non-spontaneous
