plz solve it using software POLYMATH plzzzz

Problem 2 Statement: The one-dimensional model for a tubular reactor with A Products, can be written as below: rA=Dex22CAVxCA Where, De= Dispersion coefficient of reactant A=0.01cm2/sec V= Fluid flow velocity =0.1cm/sec CA= Concentration of reactant A x= Dimension along the reactor. rA= reaction rate =(kCA) k= reaction rate constant =1.5103s1 Comp A concentration at the start of the reactor equal to 1mol/cm3 at the end of the reactor CA is minimum. This will give the following boundary condition: CA(x=0)=1dxdCA=0 If the reactor length =30cm, Obtain the steady state concentration profile
