For a specific molecule, the energy difference between the homo and lumo is 2.50 ev. what wavelength (in nm) will there be a maximum absorbance? do not include units in the answer and report to three significant figures.

The wavelength at which maximum absorbance will be seen is 496.6 nm.

Explanation:

The energy difference between the HOMO and LUMO =E = 2.50 eV

The wavelength at which maximum absorbance will be observed is related to energy of the difference of the HOMO and LUMO.

E = energy of photon of related to wavelength

h = Planck's constant =

c = speed of light =

= wavelength = ?

E = 2.50 eV =

The wavelength at which maximum absorbance will be seen is 496.6 nm.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
