Question
Electromagnetic radiations of wavelength 242 nm is just sufficient to ionise Sodium atom. Then the ionisation energy of Sodium in kJ mole-1 is.
Options
A.494.65
B.400
C.247
D.600
Solution
I.E. of one sodium atom = 
& I.E. of one mole Na atom =
NA = 
= 494.65 kJ.mol.
& I.E. of one mole Na atom =
NA = = 494.65 kJ.mol.Create a free account to view solution
