A researcher is trying to grow a single crystal from a supersaturated solution of bulk concentration C_bulk.

In her first experiment, the radius of the seed crystal used was 3.2x10^-8m.

In her second experiment, the radius of the seed was 2.16x10^-8m.

Let be a constant, a = 2/RT, determined by the surface energy of the crystal , the molar volume and the product of the ideal gas constant and the absolute temperature RT. Let C be the equilibrium solubility over a crystal with a radius of curvature r = .

We are given the following: C=1.0x10^-5 mol/L

=1.0x10^-8m

C_bulk=1.5x10^-5 mol/L =1.5C

In which case did the seed grow? Provide a description of your analysis along with the equations you used. Explain in a few sentences.
