Which statement is true of a galvanic cell?

Which of the following differences between galvanic cells and electrolytic cells is false?

$Li^{+}_{(aq)} + e^- \rightarrow Li_{(s)}$ $\varepsilon ^o = -3.04$

$Mg^{2+}_{(aq)} +2e^- \rightarrow Mg_{(s)}$ $\varepsilon ^o = -2.38$

For the following reaction to occur does the does the electrochemical cell voltaic or galvanic?

$2Li_{(s)} + Mg^{2+}_{(aq)} \rightarrow 2Li^{+}_{(aq)} + Mg_{(s)}$
