Use the w, of 0.121min from the chromatogram above to find the plate height for benzene. a) 0.493 mm b) 0.455mm c) 0.934mm d) 0.439 e) insufficient information provided n - 5.55 (++) ² = 66049.5 h - 1 - / - 0.454mm

The plate height for benzene is 0.455mm

Explanation:

Where, N = theoretical plate

= retention time

= Half of the width of the peak at it’s base

L = length of the column

H = Plate height

Since, there is no attached chromatogram so it can’t evaluate the value ofand

Putting the values in the above mentioned formulae

Hence, N = 66049.5

H =

=

= 0.45mm

Hence, the plate height of benzene is 0.455mm
