please help with this question. Notice that the reaction is second order. Thank you.

Consider the liquid phase cis - trans isomerization of 2-butene which we will write symbolically as secondoyderAB The reaction is which the volumetric flow rate, v, is constant, i.e., v=v0. 1. Sketch the concentration profile. 2. Derive an equation relating the reactor volume to the entering and exiting concentrations of A, the rate constant k, and the volumetric flow rate v0. 3. Determine the reactor volume, V1, necessary to reduce the exiting concentration to 10% of the entering concentration, i.e., CA=0.1CA, when the volumetric flow rate v0 is 10dm3/min (i.e., liters /min ) and the specific reaction rate, k, is 0.23min1
