4. For the autoionization of water: 2 H2O(l) <=> H30+(aq) + OH*(aq) the equilibrium constant Kw is 1. 139 x 10-15 at 273.15 K and 9.614 x 10-14 at 333.15 K. Assume that AH° and ASº for this process are independent of temperature from 273 to 333 K. a) Determine AH° and ASº for the autoionization process. b) If the pH of pure water were 7.000 this would imply that Kw...

1. Provide a mechanism for the formation of the compound from
its biosynthetic precursors. (I believe it has to do with starting
units and extender units and built in a similar way that fatty
acids are made?)
