Chapter 5, Problem 80QP

Consider the following double-displacement reactions. For each, identify the driving force that causes the reaction to go to completion.

$\begin{array}{l}\left(\text{a}\right){\text{ Al}}_{\text{2}}{\text{O}}_3\left(s\right){\text{ + 3H}}_{\text{2}}{\text{SO}}_{\text{4}}\left(aq\right)\to {\text{Al}}_{\text{2}}{\left({\text{SO}}_{\text{4}}\right)}_{\text{3}}\left(aq\right){\text{ + 3H}}_{\text{2}}\text{O}\left(l\right)\hfill \\ \left(\text{b}\right){\text{ CaCO}}_{\text{3}}\left(s\right){\text{ + H}}_{\text{2}}{\text{SO}}_{\text{4}}\left(aq\right)\to {\text{ CaSO}}_{\text{4}}\left(s\right){\text{ + H}}_{\text{2}}\text{O}\left(l\right){\text{ + CO}}_{\text{2}}\left(g\right)\hfill \\ \left(\text{c}\right){\text{ BaCl}}_{\text{2}}\left(aq\right){\text{ + Na}}_{\text{2}}{\text{SO}}_{\text{4}}\left(aq\right)\to {\text{ BaSO}}_{\text{4}}\left(s\right)\text{ + 2NaCl}\left(aq\right)\hfill \end{array}$
