Web1. Photochemical dissociation of oxygen results in the production of two oxygen atoms, one in the ground state and one in the excited state. O2 hv → → hv O→O*. The maximum wavelength () needed for this is 174 nm. If the excitation energy O→O* is 3.15 x 10-19 J. How much energy in kJ mole-1 is needed for the dissociation of one mole of ... WebThe features of multiphase reaction media using water (bulk water, supported thin aqueous phase) and dense phase carbon dioxide are reviewed for selective hydrogenation of carbonyl, nitro, and cyano compounds. The interface of aqueous and organic phases is important in determining the rate of hydrogenation and the product selectivity.
