• A. the size of paper used
• B. Rf values of solutes
• C. temperature of the experiment
• D. size of the chromatographic tank used

Answer 1

The correct option is B Rf values of solutes

Retention factor In chromatography, the retardation factor (R) is the fraction of an analyte in the mobile phase of a chromatographic system. In planar chromatography in particular, the retardation factor R is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front.
