Chloroform has `DeltaH_("vaporization")=29.2 kJ//"mol"` and boils at `61.2^(@)C`. What is the value of `DeltaH_("vaporization")=29.2 kJ//"mol"` for chloroform ?

A

`87.3 J//mol-K`

B

`477.1 J//mol-K`

C

`-87.3J//mol-K`

D

`-477.1 J//mol-K`

Text Solution

Verified by Experts

The correct Answer is:
1
`DeltaS_("vap") =(DeltaH_("vap"))/(T_(b))`
`=(29.2 xx 1000)/(334.2)`
`= (292000)/(3342)`
`87.3 JK^(-1)mol^(-1)`
