Exercise: Arrhenius

For hornblende, a frequency factor D₀ of 0.06 cm²/sec and an activation energy of 280 kJ/mol are assumed for the diffusion of argon. Plot the D value using the Arrhenius relationship

(a) in a diagram D on the y-axis versus T on the x-axis (use a temperature range of 300-800°C), and

(b) in a diagram lnD on the y-axis versus 1/T on the x-axis (same temperature range).

The gas constant for ideal gases is 8.314 J/mol K.

Additional information: As usual, take care of the units!

Provide the answer as a PDF please, or as a scan if solved by hand. Not only provide the result, but also the way you did the calculation!

Please note: If not stated otherwise, the exercises have to be solved before the next lecture starts, and need to be uploaded in time in OPAL, preferrably as a PDF document. Submitting spreadsheet files is permitted.

The file name of the PDF file with the solution of each exercise has to meet the following convention:
"Name_Surname_Matr.Nr._Exercise_Exercise-Number.pdf" or "..._Exercise_name.pdf"
Example: "Pfaender_Joerg_0815_Exercise_1.pdf" or "..._Exercise_REE.pdf"

Note that solving the exercises is obligatory to be accepted for the written or oral examination. At least 50% of the exercises have to be solved correctly, and the result will count by 20% to the final grade. If written explanations are required for selected exercises, do not exceed the maximum number of words allowed, otherwise the exercise counts as failed. Try to be concise in your text, with as many information as possible within a minimum of text.
