Factors that Influence Diffusion III Carbon is allowed to diffuse through a steel plate 13-mm thick. The concentrations of carbon at the two faces are 0.702 and 0.110 kg of carbon per m³ of iron, which are maintained constant. If the preexponential and activation energy are 6.5 x 10^-⁷ m²/s and 82 kJ/mol, respectively, calculate the temperature (in K) at which the diffusion flux is 3.2 x 10-⁹ kg/(m²-s).
