H� H2 - Remember I:!.G = M/- TM? Thermodynamics of a reaction depend on the sign and magnitude of AG. As temperature increases, the entropy term grows in importance. In ether formation, the I:!.S is small because two molecules of alcohol give one molecule of ether plus one molecule of water-no net change in the number of molecules. In dehydration, however, one molecule of alcohol generates one molecule of alkene plus one molecule of water-a large increase in entropy. So TI:!.S is more important for dehydration than for
