Recent kinetic measurements of the oxidation of linoleic acid by soybean lipoxygenase show that the thermal rate constants, kH ) 280 ((12) s -1 and kD ) 5.0 ((0.1) s -1 , are weakly temperature dependent within the temperature interval 30-50 °C. The

Rate data for the hydrolysis of isopropyl bromide in deuterium oxide are determined over a temperature of 35 to 80 deg . By comparison with earlier data for hydrolysis in water, it was shown that the solvent isotope effect (k/sub D// sub 2//sub O// k

The Gross-Butler theory for the solvent isotope effect of deuterium on acid-catalyzed reaction rates in thermodynamic activity function, Q' (n), for proton and deuteron at 25 deg are derived from experimental data by using the correct value for the i
