Melting & boiling point of NaCl respectively are 1080 K & 1600 K. `Delta S` for stage -I & II in
`NaCl(s) underset(Delta H fus=30 KJ)overset(I)rarrNaCl(l) underset(Delta H_(vap)=160 KJ)overset(II)rarrNaCl(g)`

A

`{:(Delta S(I) (KJ//mol//K),Delta S(II)(KJ//mol//K)),(1//36,1//10):}`

B

`{:(Delta S(I) (KJ//mol//K),Delta S(II)(KJ//mol//K)),(36,100):}`

C

`{:(Delta S(I) (KJ//mol//K),Delta S(II)(KJ//mol//K)),(1//36,10):}`

D

`{:(Delta S(I) (KJ//mol//K),Delta S(II)(KJ//mol//K)),(36,1//10):}`
