Please explain this question.

Question 3. Using the solution for Fick's second law, as presented in the notes, to analyze how a concentration boundary layer from a surface to a distance of your choosing evolves from t=0 5105cm2s1 a). Present a plot using distance as the x-axis and concentration as the y-axis to show 5 different time intervals as curves. Select your distance range and time intervals such that you can clearly quantify how the concentration boundary layer grows with time. c(x,t)=cs(csco)erf[(2Dt)x] b). Provide values for the concentration boundary layer thickness for each time interval you select
