Chapter 18, Problem 67E

Interpretation Introduction

Equilibrium constant for each of the following reaction is to be calculated.

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

b) ${\text{Br}}_{\text{2}}\left(\text{l}\right)+{\text{2Cl}}^{-}\left(\text{aq}\right)\to {\text{2Br}}^{\text{-}}\left(\text{aq}\right)+{\text{Cl}}_2\left(\text{g}\right)$

c) ${\text{MnO}}_{\text{2}}\left(\text{s}\right)+{\text{4H}}^{+}\left(\text{aq}\right)+\text{Cu}\left(\text{s}\right)\to {\text{Mn}}^{\text{2+}}\left(\text{aq}\right)+{\text{2H}}_2\text{O}\left(\text{l}\right)+{\text{Cu}}^{2+}\left(\text{aq}\right)$
