1 Department of Chemical Engineering Spring, 2009 University of California, Santa Barbara CHE 140A Problem Set No. 1 Due Tuesday, April 7, 2009 Problem 1: Fogler, 1-6, p. 30 Calculate the volume of a CSTR for the conditions used to figure the plug-flow reactor volume in Example 1-1. Which volume is larger, the PFR or the CSTR? Explain why. Problem 2: Fogler, 1-7, p. 30 Calculate the time to reduce the number of moles of A to 1% of its initial value in a constant-volume batch reactor for the reaction and data in Example 1-1. Problem 3: Fogler, 1-8, p. 30 What assumptions were made in the derivation of the design equations for: (a) a batch reactor? (b) a CSTR? (c) a plug-flow reactor (PFR)? (d) a packed-bed reactor (PBR)? (e) State in words (using complete sentences) the meanings of , A r , A r and . A r Is the reaction rate A r an extensive quantity? Explain.
