Question

A radiation which has an energy of N 50 kJ/mol

falls in the following region of electromagnetic

radiations :

(a) infrared (b) visible

(c) ultraviolet (d) microwave​

Answer 1

Answer:

Option A is correct

Explanation:

Electromagnetic spectrum illustrates all the possible electromagnetic radiations, their categorization on the basis of energies, frequencies, wavelenghths.

Now in electromagnetic spectrum, energy is expressed in electron volt. So first we convert KJ to eV

1 Joule = 6.242e+18

1eV = (1.60217733×10^-22) × (6.0223×10^23)

      =96.49kj/mole

It means 50KJ/mole = 0.485 eV

This eV falls in the infra red radiation

Hence Option A is correct
