Question 2 The reaction AB is carried out in a laboratory reactor. According to a published article the concentration of A should vary with time as follows: CA=CA0ekt where CA0 is the initial concentration of A in the reactor and k is a constant. a) If CA and CA0 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) : Verify the proposed rate law graphically (first determine what plot should yield a straight line), and calculate CA0 and k. 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=265s
