Answer:

Pentafluorobenzene: 11,92 min

Benzene: 12,14 min

Explanation:

Retention time of pentafluorobenzene is 12,98 min and 13,20 min of benzene.

The adjusted retention time is the time an analyte spends in the column not the stationary phase. As time of unretained solute is 1,06 min the adjusted retention time for an analyte is:

tr' = tr - 1,06min

For pentafluorobenzene:

tr' = 12,98min - 1,06min = 11,92 min

For benzene:

tr' = 13,20 - 1,06min = 12,14 min

I hope it helps!
