A sheet of bcc iron 2.0 mm thick was exposed to a carburizing gas atmosphere on one side (i. e., a gas like methane that provides a flux of carbon atoms into the material) and a carburizing atmosphere on the other side at 675 o C. After having reached steady state, the iron was quickly cooled to room temperature. The carbon concentrations at the two surfaces of the sheet were determined to be 0.015 and 0.0068 wt. %, respectively. Compute the diffusion coefficient if the steady state diffusion flux was 7.36 x 10-9 kg/m2 -s
