A chemical reaction A→B is carried out in a closed vessel. The following data are taken for the concentration of A, CA(g/L), as a function of time, t(min), from the start of the reaction. CA (g/liter) CAO CAE time (min) Ca (g/L) 0.2823 7(min) 36.0 0.18390 65.0 In 0.13550 100.0 0.09980 = = - kt 160.0 A proposed reaction mechanism predicts that CA and t should be related by the expression CA - CAe Cao – CAe. - 0.06980 0.0495 where k is the reaction rate constant. a) Plot the data appropriately to determine the value of k. Report the Value of k b) If the tank volume is 125.0 L and there is no B in the tank at t = 0, how much B(g) does the tank contain after 2.00 hours? c) Estimate the times required for the final concentration of A to reach 1.10, 1.05, and 1.01 times C'Ae at t = t₁, t2, and t3 respectively. (Those estimates depend upon the exact value of k used.) Report t₁, t2, and t3, and the mass of B produced at each time.
