![Determine Ecel for the reaction: 2 Ag* + Mg – 2 Ag + Mg²* if the concentration
of the Ag* is 0.250 M while that of the Mg*2 is also 0.250 M. Tis at 298.15 K.
Write your answer in 3 significant figures, with positive or negative sign: Example: +3.34 (no need to put volts
or V).
The standard half reduction reactions are:
Mg2*(aq) + 2 e- → Mg(s)
E° = -2.356 V
Ag*(aq) + e- → Ag(s)
E° = 0.800 V
