It is believed that the adsorption equilibrium constant for cyclo- hexanol is around I and is roughly one or two orders of magnitude greater than the Webcyclohexanol. Finally, it should be noted that this type of dehydration reaction is entirely reversible. In fact, if you read the mechanism shown in equation 2 from right to left, you may recognize it as the acid-catalyzed hydration of an alkene! The position of this equilibrium is strongly dependent upon the reaction conditions.
