Study Notes
Molecular Diffusion
- The main factor affecting the rate of molecular diffusion is the concentration gradient.
Net Flux of Molecules
- Diffusion explains the net flux of molecules from an area of higher concentration to an area of lower concentration.
Process Governing Molecular Diffusion
- Once the concentrations are equal, the process governing molecular diffusion is random molecular motion.
Result of Diffusion
- The result of diffusion is the uniform distribution of molecules throughout the system.
Result in Uniform Temperature and Absent External Net Forces
- In a phase with uniform temperature and absent external net forces, the result of molecular diffusion is called equilibrium.
