Would you expect the crystal on the right to be more or less stable enthalpically (AH)? A. Less stable B. More stable C. Equal AH Ostwald ripening Nature Materials 1.205 - 206 (2002) At equilibrium, why would small crystals get smaller and bigger crystals get bigger? (Grey and Green are the same molecules, just from different crystals) A. The molecules at the periphery have less enthalpic stabilization. Ostwald ripening maximizes enthalpic stabilization B. The molecules at the periphery of the...

You would expect a bond of an Eastern European government to pay interest rate as compared to a bond of the U.S. government. You would expect a bond that repays the principal in year 2040 to pay interest rate as compared to a bond that repays the principal in year 2020. You would expect a bond from a software company you run in your garage and a bond from Coca-Cola to pay different interest rates because of differences in the...

6.2. Germanium is an interesting semiconductor because it has a small band gap (Eg 0.67eV). As a result, it has a higher intrinsic concentration ni than either silicon or GaAs. Do you expect the conductivity of intrinsic germanium to be less than or greater than that of intrinsic silicon? How about compared to GaAs? Explain Why?

A certain temperature and volume would you expect the pressure
of a given number of moles of KR or CCL4 to deviate more from ideal
behavior? why?
O O O CCI, because it occupies a larger volume and has smaller dispersion forces between molecules. CCl4 because it occupies a smaller volume and has greater dispersion forces between molecules. CCl4 because it occupies a larger volume and has greater dispersion forces between molecules. Kr because it occupies a smaller volume and...
