A galvanic cell is Mn(s) ∣ Mn2+(aq) ∣∣ Cu2+(aq) ∣ Cu(s)\text{Mn}(s)\,|\,\text{Mn}^{2+}(aq)\,||\,\text{Cu}^{2+}(aq)\,|\,\text{Cu}(s) with overall reaction Mn(s)+Cu2+(aq)→Mn2+(aq)+Cu(s)\text{Mn}(s)+\text{Cu}^{2+}(aq)\rightarrow \text{Mn}^{2+}(aq)+\text{Cu}(s). The reaction is spontaneous under standard conditions. The cell is prepared with [Mn2+][\text{Mn}^{2+}] = 1 M and [Cu2+][\text{Cu}^{2+}] much larger than 1 M. Using qualitative Nernst reasoning about QQ relative to 1, what happens to EcellE_\text{cell} and spontaneity?
