Chapter 17, Problem 24E

For each reaction listed, determine its standard cell potential at 25 °C and whether the reaction is spontaneous at standard conditions.

(a) $\text{Mn}\left(s\right)+{\text{Ni}}^{2+}\left(aq\right)\to {\text{Mn}}^{2+}\left(aq\right)+\text{Ni}\left(s\right)$

(b) ${\text{3Cu}}^{2+}\left(aq\right)+2\text{Al}\left(s\right)\to 2{\text{Al}}^{3+}\left(aq\right)+3\text{Cu}\left(s\right)$

(c) $\text{Na}\left(s\right)+{\text{LiNO}}_3\left(aq\right)\to {\text{NaNO}}_3\left(aq\right)+\text{Li}\left(s\right)$

(d) $\text{Ca}{\left({\text{NO}}_3\right)}_2\left(aq\right)+\text{Ba}\left(s\right)\to \text{Ba}{\left({\text{NO}}_3\right)}_2\left(aq\right)+\text{Ca}\left(s\right)$
