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

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
