No. As others have said, most reactions will go to equilibrium. Some go to completion. There are even reactions (like the Zabotinsky-Belusov reaction) that actually oscillate back and forth! Really! Check this out...

Dav- entropy only applies to a defined & specific system...

No, most chemical reactions in fact do not go to completion. The degree to which any reaction occurs can be calculated using thermodynamic formulas (entropy and enthalpy) combined with the law of mass action.
Values for how complete a reaction is are called K values. These are very useful for finding out the degree to which a reaction occurs. You can calculate K values with a table of entropies and enthalpies of the different substances you are using, along with thermodynamic formulas.
However, you cannot calculate the rate at which such reactions will occur. Rate laws can only be determined by experiment.

Chemical reactions go to completion when a gas is given off, or a precipitate is formed taking those materials out of the reaction. If a reactant is used up the reaction will stop. Otherwise they go to an equlibrium.

No.
Most reactions proceed to equilibrium.
Look up Le Chetalier's principle.

Yes, matter seeks entropy.
