At t = 0, a 5 cm thick plate of pure terpium is put into a furnace at 1000 °c with a carbon atmosphere that creates a surface concentration of 2 wt % at both the front and back surfaces. the diffusion coefficient for carbon in terpium at this temperature is 2.5 x 10-9 m2/s. assume that diffusion only occurs into the thickness of the plate but from both directions. (hint: it may to sketch the system). a. on the template below, sketch the c concentration profile in the material at t = 0. (3 pts) b. add values to the vertical axis. (2 pts) c. add a qualitative sketch of the c concentration profile after a short time, t1. (4 pts) d. add a qualitative sketch of the c concentration profile at a later time t2 (3 pts)
