Chapter 17.5, Problem 17.8P

Predict from Table 17.1 whether each of the following reactions can occur under standard-state conditions:

1. (a) $2{\text{Fe}}^{\text{3+}}\left(aq\right)+2{\text{I}}^{-}\left(aq\right)\to 2{\text{Fe}}^{\text{2+}}\left(aq\right)+{\text{I}}_{\text{2}}\left(s\right)$
2. (b) $3\text{Ni}\left(s\right)+2{\text{Al}}^{\text{3+}}\left(aq\right)\to 3{\text{Ni}}^{\text{2+}}\left(aq\right)+2\text{Al}\left(s\right)$

Confirm your predictions by calculating the value of E° for each reaction. Which reaction(s) can occur in the reverse direction under standard-state conditions?
