A certain molecule, let's call it DDT, is great for insect control but at higher concentrations nas been shown to be harmful to larger creatures (thinning of eggshells in bird and a carcinogen in mammals). DDT decomposes with a rate constant of 1.24 x 102 days!. If a lake has been contaminated, (DDT) = 8.75 x 10% M, how many days will it take for the [DDT] to reach 1.41 x 10M(the "safe concentration for mammals)? Show whether or not the proposed mechanism is consistent for the following chemical reaction and observed rate. 2NO(g) + Brz(g)(aq) → 2NOBr(g) Rate = k[NO] [Br2] Proposed Mechanism Step 1: NO(g) + Bra(g) - NOBr2 (Fast) Step 2: NOBr2(g) + NO(g) → 2NOBr (Slow)
