What is the melting point of benzene if `DeltaH_("fusion")= 9.95kJ//mol` and `DeltaS_("fusion")= 35.7J//K-"mol"`

A

`278.7^(@)C`

B

`278.7^(@)K`

C

300 K

D

298 K

Text Solution

Verified by Experts

The correct Answer is:
B
at M.P. `DeltaS_("fusion")=(DeltaH_("fusion"))/(T)`
`implies" "T=(DeltaH)/(DeltaS)=(9.95 xx1000)/(35.7)=278.7 K`
