3. (2pts) The reaction A → B is carried out in a laboratory reactor. According to a published article the concentration of A should vary with time as follows: CA = CAO exp(-kt) where CÃO is the initial concentration of A in the reactor and k is a constant. a. If CA and CÃo are in lb-moles/ft³ and t is in minutes, what are the units of k? b. The following data are taken for Ca(t) t (min) CA (lb-mole/ft³) 0.5 1.02 1.0 0.84 1.5 0.69 2.0 0.56 3.0 0.38 5.0 0.17 10.0 0.02 Verify the proposed rate law graphically (first determine what plot should yield a straight line), then calculate CAO and k. This is best done in a spreadsheet (e.g. Excel). c. Convert the formula with the calculated constants included to an expression for the molarity of A in the reaction mixture in terms of t (seconds). Calculate the molarity at t = 265 s.
