10.34 – Fall 2006 Homework #11 Due Date: Mon day, December 11 th , 2006 – 9 AM Kinetic Monte Carlo The oxidation of an organic droplet of diameter D in air-saturated water containing an antioxidant can be modeled with these reactions: () ROOH + 2 RH + O 2 2 2 1 2 ROO + ROH + H O () ROO + RH + O 2 ROOH + ROO 2 () 2 ROO ROH + O 2 + aldehyde 3 If the radical site on the ROO reaches at the surface of the droplet, it can react with the aqueous antioxidant: 4 ROO + X ROOH + X i () ( aq ) ( aq ) Note that the second reaction is the radical-catalyzed oxidation of the organic, and the other reactions create or destroy the catalyst ROO. The back reactions are negligible under the reaction conditions of interest. These equations are good models for the unhealthful oxidation of lipoprotein leading to arteriosclerosis, for reactions important in emulsion polymerization, and for the oxidative degradation of several commercial products. For initial conditions, take [ROOH]=10 -6
