Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2/s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10-9kg/m2-s.

T=575.16K

Explanation:

To solve the problem we proceed to use the 1 law of diffusion of flow,

Here,

is the rate in concentration

is the rate in thickness

D is the diffusion coefficient, where,

Replacing D in the first law,

clearing T,

Replacing our values

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

the answer should be in the picture.
