The change in molar enrgy noticed during atomic transimission of 5 hertz frequency from a monoatomic molecule :

A

`33xx . 1 xx 10^(-34) J`

B

` 1.99xx 10^(-9) J`

C

`30.1xx 10^(-9)J`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`E= N. h.v`
`=6. 023 xx 10^(23) xx 6.624 xx 10^(-34) xx 5`
` = 1.99 xx 10^(-9) j//mol`.
