Question: Carbon is allowed to diffuse through a steel plate 10 mm thick. The concentrations of carbon at the two faces are 0.85 and 0.40 kg

Carbon is allowed to diffuse through a steel plate 10 mm thick. The concentrations of carbon at the two faces are 0.85 and 0.40 kg C/cm3 Fe, which are maintained constant. If the pre-exponential and activation energy are 5.0 × 10-7 m2/s and 77,000 J/mol, respectively, compute the temperature at which the diffusion flux is 6.3 × 10-10 kg/m2.s?
