Which risk significantly increases when molecular diffusion rates decrease within a chromatographic column?

A)Peak broadening becomes more pronounced
B)Column pressure remains relatively stable
C)Separation efficiency sees improvement overall
D)Analyte resolution shows unexpected increase

💡 Explanation

Decreased molecular diffusion limits analyte interaction with the stationary phase relying upon mass transport rates; this causes peak broadening because analytes elute in a wider time range, therefore increased band broadening; rather than increased resolution.
