In the nuclear fusion reaction `""_(1)^(2)H+""_(1)^(3)H to ""_(2)^(4)He+n`
given that the repulsive potential energy between two nuclei is `-7.7 xx 10^(-14)J,` the temp. at which gases must be heated to initiate the reaction is nearly : `(k=1.38 xx 10^(-23))`

A

`10^(7)K`

B

`10^(3)K`

C

`10^(9)K`

D

`10^(7)K`

Text Solution

Verified by Experts

The correct Answer is:
C
Energy `=3/2kT`
`T=2/3. (7.7 xx 10^(-14))/(k) =2/3 xx (7.7 xx 10^(-14))/(1.38 xx 10^(-23))=10^(9)K`
