arbon is allowed to diffuse through a steel plate 15 mm thick, The concentration of carbon at the faces is 0.05 and 0.30 kg C/m³ Fe, which are maintained constant. If the pre-exponential and activation energy are 5.2 x 10-7 m/s and 80,000//mol respectively, Find: Compute the temperature at which the diffusion flux is 1.43 x 10 0-9 kg m2s At approximately what temperature would a specimen of y - iron have to be carburized for 2 h to produce the same diffusion result as at 900°C for 15 h?

I want the answer by handwriten please
Carbon is allowed to diffuse through a steel plate 15 mm thick. The concentration of carbon at the facesS 0.65 and 0.30 kg C/m3 Fe, which are maintained constant, If the pre-exponential and activatioon energy are 6.2 x 10-7 m/s and s0,000//mol respectively, Find: mol Compute the temperature at which the diffusion flux is 1.43 x 10-9 KB m²s At approximately what temperature would a specimen of y - iron have to be carburized for 2 h to produce the same diffusion result as at 900°C for 15 h?
