CHM1011 Lecture Notes - Lecture 11: Reaction Rate, Stoichiometry, Phenolphthalein

A rapid reaction does not necessarily mean that it goes to completion. Sparingly soluble PbI 2 rapidly dissociates to Pb and I ions in water, but only to a small extent! In Weeks 7 8 we talked about thermodynamics, which ...
