Hope to get help for the homogeneous nucleation problem. Thanks!
Homogeneous nucleation can occur on surfaces as well as in bulk. For
example, a thin film of gold is being deposited from a gold-containing
electrolyte solution on a silver substrate, where the gold forms circular
patches of fixed thickness on the surface. The driving force for gold
deposition is g and the edge energy for the gold patches is ?.
Write the energy change associated with creating a gold patch with size of
size r. Plot this energy change as a function of r. What is the critical radius
for the nucleus? Find an expression for the energy required to form a
