Q$2$: A chromatogram of a two$-$component mixture on a $25cm-$packed liquid chromatography column is shown below, The flow rate was $0\mathrm{.}4m\frac{l}{m}in$

a$)$ Find the retention times for A and $B.$

b$)$ Calculate the relative retention $($ selectivity $)$ for A$,$ B

c$)$ Calculate the capacity factor $K$ for A and $B$

d$)$ Find the average number of plates for the column

e$)$ Find the average plate height

f$)$ Calculate the resolution $(R_s)$ for $A,B$

$R_s=\frac{2[(t_R{)}_B-(t_R{)}_A]}{W_A+W_B}$
