Explain why this isobserved.b) The two chromatograms were collected with the same instrument, including column and detector.Suggest something that was different in B (compared to A) that allowed more of the lower and highermass hydrocarbons to be separated.c)Consider chromatogram B. If the concentrations of each hydrocarbon in the mixture are all thesame, why do the peak areas of cach hydrocarbon differ markedly?

The objective of this question is to show the chromatogram A and broadening peaks indicate possible…
