Question- A voltaic cell is constructed that uses the following reaction and operates at 298 K. (Ered Ni+2 is -0.277) Zn(s) + Ni2+(aq) Zn2+(aq) + Ni(s) (a) What is the emf of this cell under standard conditions? Correct: Your answer is correct. V (b) What is the emf of this cell when [Ni2+] = 3.98 M and [Zn2+] = 0.184 M? V (c) What is the emf of the cell when [Ni2+] = 0.292 M and [Zn2+] = 0.808 M? V
