Problem

Consider a galvanic cell constructed from the following half-reactions at 298 K. Ag

^{+}

+ e

^{-}

→ Ag(s)

E^{\circ}=+0.80\,\text{V}

^{2+}

+ 2 e

^{-}

→ Zn(s)

E^{\circ}=-0.76\,\text{V}

What is the value of

E^{\circ}_{\text{cell}}

for the overall cell reaction? (a)

+0.04\,\text{V}

(b)

-1.56\,\text{V}

(c)

+1.56\,\text{V}

(d)

+0.80\,\text{V}
