Chapter 13, Problem 13.40PAE

Calculate the equilibrium constant for the following reactions using data from the standard reduction potential tables.

(a) ${\text{Cl}}_{\text{2}}\left(\text{g}\right)+2{\text{Br}}^{\text{-}}\left(\text{aq}\right)\to {\text{Br}}_{\text{2}}\left(\text{g}\right)+2{\text{Cl}}^{\text{-}}\left(\text{aq}\right)$

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

(c) ${\text{I}}_{\text{2}}\left(\text{s}\right)+{\text{Sn}}^{\text{2+}}\left(\text{aq}\right)\to 2{\text{I}}^{-}\left(\text{aq}\right)+{\text{Sn}}^{\text{4+}}\left(\text{aq}\right)$
