A galvanic cell operates using the half-cells Cd(s)∣Cd2+(aq)\text{Cd}(s)|\text{Cd}^{2+}(aq) and Ag+(aq)∣Ag(s)\text{Ag}^+(aq)|\text{Ag}(s). The spontaneous overall reaction under standard conditions is Cd(s)+2Ag+(aq)→Cd2+(aq)+2Ag(s).\text{Cd}(s)+2\text{Ag}^+(aq)\rightarrow \text{Cd}^{2+}(aq)+2\text{Ag}(s). Compared with standard conditions, the Ag+\text{Ag}^+ concentration is increased above 1.0 M1.0\,\text{M} while all other species remain at standard conditions. Using qualitative Nernst reasoning (by comparing QQ to its standard-condition value), what happens to EcellE_\text{cell} and spontaneity?
