|Reactions That Run To Completion|
|There are some reactions that are considered to run to
They do not set up an equilibrium but run until one of the reactants
out. They basically fall into 3 basic categories.
|1. Formation of a gas that is allowed to escape.
Sugar -------> CO2
|2. Formation of a precipitate
2 Tl+ + 2 Cl- -----> 2 TlCl (ppt)
The ppt is a solid that makes the equation heterogenous and
eliminates the TlCl from the Keq equation.
|3. Formation of a slightly ionized product.
NaCl(s) + KBr(s) --H2O--> Na+(aq) + Cl-(aq) + K+(aq) + Br-(aq)
Remove water and you would get a mixture of four products
two. You would get NaCl, NaBr, KBr,& KCl
