What is the term for a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane?
1. Osmosis
2. Diffusion
3. Dialysis
4. Filteration

What is the relation between concentration of reactants and the rate of chemical reaction?
