Achemical 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: ca0 ca0 cae cae ca (g/liter) ca(g/liter) t(min) t(min) 0.1823 0.1453 0.1216 0.1025 0.0795 0.0495 0 36 65 100 160 [infinity] a proposed reaction mechanism predicts that ca and t should be related by the expression ln ca cae ca0 cae kt where k is the reaction rate constant. (a) do the data support this prediction? if so, plot the data appropriately to determine the value of k. (b) if the tank volume is 125 l and there is no b in the tank at t 0, how much b(g) does the tank contain after two hours? (c) estimate the time required for the final concentration of a to reach 1.1, 1.05, and 1.01 times cae, and determine the mass of b produced at each of these conditions for the reactor described in part (b).
