A sample containing anthracene dissolved in methane was separated using gas chromatography on a column with mobile phase (Vm) and stationary phase (Vs) volumes of 27.5 mL and 11.0 mL, respectively. For this particular column, anthracene has a retention volume (Vr) of 72.6 mL. Calculate the retention factor (k) and the partition coefficient (K) for anthracene in this separation.
