... “B” is the fastest reaction because aqueous ions are highly mobile and more concentrated than molecules in a gas. The aqueous ions have a high probability of colliding. Also, when Ag+ and Ireact, there are no bonds to break. They simply collide and bond to form the solid. (The activation energy is v ...

Equilibrium chemistry
Equilibrium chemistry is a concerned with systems in chemical equilibrium. The unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero. This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Applications include acid-base, host-guest, metal-complex, solubility, partition, chromatography and redox equilibria.
