Provide 2 differences between Ductile and Brittle fracture

When two components (pure metals) completely mix in each other as a solid-solution, it means their solid-solubility is 

For highly ductile metal the percentage reduction in area will be close to

Are cold work metals suitable for high-temperature service? Why or Why not? Provide a clear explanation on what happens in the material by explaining the start and end microstructure.

Why would drilling a hole at the end of a crack prevent crack propagation?

This is an example of an essay question. Use the text-entry field below to write a paragraph to submit as your answer.

You convert cyclopentane into pentane and generate the following rate data: T(K) k (s-1) 750 1.8 x 10-4 850 2.7 x 10-3 900 3.0 x 10-2 950 0.26 From the data and plot, determine the order and calculate the activation energy for the reation.

The tabulated data show the concentration of AB versus time for this reaction: AB (g) → A (g) + B (g) Time (s) [AB] (M) ​ Time (s) [AB] (M) 0 0.950 ​ 200 0.180 50 0.459 ​ 250 0.149 100 0.302 ​ 300 0.128 150 0.225 ​ 350 0.122 Using the plot of 1/[AB] with respect to time (s), determine the rate law for the reaction.
