What is the calculated value of the cell potential at 298 K for an electrochemical cell with the following reaction, when the Hg+ concentration is 1.21 M and the Zn+ concentration is 9.10 10-4 M? Hg+ (aq) + Zn(s) Hg(1) + Zn+ (aq) 2+ + (aq) + 2e Hg(1) F = 0.855 V red Ecell || Hg O true O false Zn+ (aq) + 2e Zn(s) E red V -0.763 V The cell reaction as written above is spontaneous for the concentrations given:
