(b) Consider the liquid phase reaction cis-trans isomerization of 2-butene The reaction is first order and is carried out in a tubular reactor in which the volumetric flow rate, v, is constant i. Sketch the concentration profile (6 points) ii. Determine the reactor volume necessary to reduce the exiting concentration to 10% of the entering concentration when the volumetric flow rate is 10dm3/min (i.e. liters /min ) and the specific reaction rate, k, is 0.23min1
