The rate constants at 400 K are k1 = 2x10-3 s-1 and k2 = 1x10-3 s-1. For a reactor operating at 400 K, the feed concentration of A is 1 mol /L, and the volumetric flow rate is 400 L/min (CR0=0 and...

The rate constants at 400 K are k1 = 2x10-3 s-1 and k2 = 1x10-3 s-1. For a reactor operating at 400 K, the feed concentration of A is 1 mol /L, and the volumetric flow rate is 400 L/min (CR0=0 and CS0=0). What is the optimum space-time (s) to maximize the yield of R? (The reactor type (PFR or MFR) should be chosen to favour the formation of R)
