Aseed crystal of diameter d (mm) is placed in a solution of dissolved salt, and new crystal are observed to nucleate (form) at a constant rate r (crystals/min). experiments with seed crystals of different sizes show that the rate of nucleation varies with the seed crystal diameter as: r(crystals/min)= 100-20d a) what are the units of the constants 100 and 20? (assume the given equation is valid and therefore dimensionally homogenous). b) calculate the crystal nucleation rate in crystal/s corresponding to a crystal diameter of 0.050 in. 3 c) derive a formula for r(crystals/s) in terms of d (in).
