Farmer Michael is developing a process in a batch reactor which can produce a new fertilizer compound. By taking secret ingredient, A, and running the reaction in a batch reactor, the decomposition product that is formed is F, which is a component of fertilizer. The reaction is A F. The rate law expression for this reaction is -r = kCA1.5. The reaction occurs in the liquid phase and it is irreversible. 1. Assume that the reactor is operated isothermally and isobarically. The feed is pure A. What is the time, t, that is needed to achieve a conversion of XA? This answer will be symbolic. (20 points)
