Homework Answers
A) Chromatogram b show better resolution that that of chromatogram a . because Peak width of the chromatogram (a) is greater that that of chromatogram (b ) as separation is not efficient of chromatogram (a) peak become broad.
Peaks from chromatogram (a) are sharp and peak width also less .
B) As particle size decrease the diffusion path lenghts are short allow to solute in and out faster .and peak dispersion become less .
Partical size of column from which chromatogram (b) is run is smaller than the other chromatogram.
