the physical and chemical properties of two chiral molecules, D and L, are identical (though there are some exceptions that we need not concern ourselves with here). That also suggests that in an arbitrary environment the two chiral molecules should be present in equal amounts. If, however, for whatever reason we start off with a quantity of some chiral material of a single chirality, say all D, then that same Second Law of Thermodynamics discussed earlier, tells us, that given enough time, that material of single chirality will become racemic, meaning that the material will end up consisting
