How Do You Calculate Hardness from Concentration Using Fick's Second Law?

You have all the necessary variables to do so. In summary, the conversation is about solving a problem involving calculating concentration and hardness as a function of depth using variables such as D, D_0, Q_d, R, and T. The problem also involves creating a graph of concentration vs depth and using it to determine hardness vs depth.

Can you explain in your own words what the problem is asking? What is happening in the steel, and what variables does the process depend on?

i am guessing that they want me to use the graph to get another plot with concentration vs depth... then from that i am to get hardness vs depth. other than that i am confused as well. i have D and D_0 and Q_d and R and T. from this i can get concentration using flicks 2nd law.. but what about hardness and all that?

It looks to me like you're supposed to calculate the concentration as a function of depth, then determine the hardness as a function of depth based on the graph of hardness as a function of concentration.
