If each nucleus can be made supercritical at a rate of f per second the homogeneous nucleation rate is given as f*C (Assume C to be the concentration of critical-sized nuclei). The value of f depends on ______
If each nucleus can be made supercritical at a rate of f per second the homogeneous nucleation rate is given as f*C (Assume C to be the concentration of critical-sized nuclei). The value of f depends on ______ Correct Answer Vibrational frequency of atoms
If the activation energy for atomic migration is ΔGm per atom, f can be written as w exp (-ΔGm/kT) where w is a factor that includes the vibration frequency of the atoms and the area of the critical nucleus.
