29. Solving a chemistry problem

5. The corrected retention time for o-xylene at a carrier gas rate of 45 mL/min is 12.9 s. On the same column, the distance from the moment of sample injection to the exit of the maximum of the p-xylene peak is 13 mm (the retention distance of the non-absorbing component is 3 mm) at a chart tape speed of 3 cm/min. The carrier gas flow rate was 30 ml/min. Determine which substance will be retained more strongly.
