If the energy different between the electronic stazte in `214.68 mol^(-1)` calculate the frequency of light emited when an electron drop form the hight to the lower state planks constant , `h = 39,79 xx 10^(-14)kJmol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`Delta E = E_(2) - E_(1) = hv`
`:. 214.68 = 39.79 xx 10^(-14) xx v`
` or v = 5.39 xx 10^(14) xx cps`
