Carbon is allowed to diffuse through a steel plate 12mm thick. The concentrations of carbon at the two faces are 0.86 and 0.41kg C/m3 in Fe, which are maintained constant. If the preexponential and activation energy are 6.2107m2/s and 80,000J/mol, respectively, compute the temperature (in K) at which the diffusion flux is 6.61010kg/m2s
