A plate of iron is exposed to a carburizing (carbon-rich) atmosphere on one side and a decarburizing (carbon-deficient) atmosphere on the other side at 800°C. The process is conducted at steady state. The mass flux of the process is 4.4 x 109 kg/(m².s). The carbon concentrations at two different regions inside the plate are 1.4 and 0.7 kg/m³. Assume the diffusivity 4 x 10-11 m²/s. What is the distance between the two different concentrations?
