`A (l) overset(1atn)hArr A(g), Delta_(vap)H = 460.6 cal mol^(-1)`, boiling point `-50K`. What is the boiling point at `10` atm

A

`150K`

B

`75 K`

C

`100K`

D

None is correct

Text Solution

Verified by Experts

`DeltaH = 2.303 R [(1)/(T_(1))-(1)/(T_(2))]"log"(P_(2))/(P_(1))`
`460.0 = 2.303 xx2 [(1)/(50)-(1)/(T_(2))] log 10`
`:. T_(2) = 100K`
