polar and nonpolar

beta or backwards reaction rate depends on

number and strength of bonds

why does hydrogen bond exist?

water molecules have a dipole, so slightly negative oxygens will bond with slightly positive hydrogens

ionic bonds

create crystals, very strong

temperature is measure of

average kinetic energy

what determines how quick a solute will diffuse?

solute size/radius, solute charge, system temperature, solvent viscosity
