A sample containing anthracene dissolved in methane was separated using gas chromatography. methane was detected at 41.3s (tM) and anthracene was detected at 200.0s (tR). The manufacturer of the column states that the volume of the mobile phase (VM) is 6.0 times the volume of the stationary phase (VS). Calculate the retention factor (k) and the distribution constant (KD) for anthracene in this separation.
