Chemistry

A mixture of benzene (C6H6), toluene (CH3C6H5) and methane (CH4)was injected into a gas chromatograph column that is12.5 m long.The peaks were observed at 40 s (methane), 260 s (benzene), and 272s (toluene).
(a) Calculate the adjusted retention time (tS) and capacityfactor (k) for each solute.
(b) Find the relative retention (ï¡) of toluene and benzene.
(c) If the width at the base (w) of the peaks for toluene andbenzene is 16 and 20 s, respectively, calculate the resolution ofthe two peaks.
(d) Calculate the number of theoretical plates and thetheoretical plate height for toluene and benzene in thisexperiment.
