Question

A galvanic cell is constructed by wiring a vanadium electrode bathed in 1.0 M V^2+ (aq) to a mercury electrode bathed in 1.0 M Hg^2+ (aq), with the two solutions connected by a salt bridge. Consider the two half reactions listed below. What is the cell voltage for this device?
V^2+(aq) + 2e^-  --->V (s)              E° = -1.130 V vs SHE
Hg^2+(aq) + 2e^-  --->Hg (l)          E° = +0.911 V vs SHE
Select one:
a. -2.041 V
b. +2.041 V
c. -1.020 V
d. +0.219 v
e. -0.219 V
