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 KD. 298 K

Answer» Correct Answer - B
at M.P. `DeltaS_("fusion")=(DeltaH_("fusion"))/(T)`
`implies" "T=(DeltaH)/(DeltaS)=(9.95 xx1000)/(35.7)=278.7 K`
