Consider the liquid phase cis - trans isomerization of 2-butene H CH, CH CH, CH, H cis-2-butene trans-2-butere which we will write symbolically as AB The reaction is first order in A (-+A= C) and is carried out in a tubular reactor in which the volumetric flow rate, o, is constant, le, U = CAO CA=0.1CAO AB V=0 V P1-1(b), (c). (b) Revisit Example 1-2. Calculate the volume of a CSTR for the conditions used to calculate the plug-flow reactor volume in Example 1-2. Which volume is larger, the PFR or the CSTR? Explain why. Suggest two ways to work this problem incorrectly. (Ans.: V CSTR = 391 m3] (c) Revisit Example 1-2. 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 same reaction and data in Example 1-2. Suggest two ways to work this problem incorrectly. (Ans.: t = 20 min) P1-5 (a), (b), (d) Note: in (d), only repeat (a) and (b)
