please use euler with matlab for solution

2- A gas stream containing A is next to a wall of length L as shown in the figure. The gas A diffuses into the porous wall from the permeable surface and a first order irreversible reaction AB with a reaction rate constant k takes place. We know by measurement that the concentration of A is zero next to the impermeable wall. The component mass balance gives the following differential equation for the concentration of A at steady-state conditions, Ddx2d2CAkCA=0 a) Write the boundary conditions for the system. b) Write a MATLAB code to solve the ODE using shooting method with explicit Euler method. c) Plot the concentration profile along the x-direction. Take length L=5cm,D=1.2104m2/s,k=0.1m3/kmol.s,CAo=48kmol/m3
