Carbon is allowed to diffuse through a steel plate 12 mm thick. The concentrations of carbon at the two faces are 0.87 and 0.42 kg C/m3 in Fe, which are maintained constant. If the preexponential and activation energy are 6.2 × 10-7 m2/s and 80,000 J/mol, respectively, compute the temperature (in K) at which the diffusion flux is 6.4 × 10-10 kg/m2-s.
