Question

Q4/ Derive briefly equations to find Critical Nucleus Radius and Activation Free Energy for stable solid particle and find it in terms of latent heat of fusion and melting temperature.​

Answer 1

Answer:

"Critical radius is the minimum particle size from which an aggregate is thermodynamically stable. In other words, it is the lowest radius formed by atoms or molecules clustering together (in a gas, liquid or solid matrix) before a new phase inclusion (a bubble, a droplet or a solid particle) is viable and begins to grow. Formation of such stable nuclei is called nucleation."
