which are converted to aluminum hydroxide. Determine the average conversion of alumina to paluminum hydroxide at the outlet of the reactor. The fraction of alumina converted in any particle depends on time, t it spends in the reactor, and the average residence time, of the particles in the reactor. particles in the reactor: X=1(18t/9)2 The RTD of alumina particles in the reactor, determined using the nulon inu of a tracer, is Tivel as
