Assuming `DeltaH^(@)` and `S^(@)` do not change with temperature. Calculate, the boiling point of liquid A using the thermodynamic data given below.

A

300 K

B

130 K

C

150 K

D

50 K

Text Solution

Verified by Experts

The correct Answer is:
A

`A(l) to A(g)` at boiling point
`DeltaH = -100 -(-130) = 30 kJ//mol, DeltaS = 200 -100 = 100 kJ//mol`
For equilibrium `DeltaG = 0 rArr T_(b) =(DeltaH)/(DeltaS) = 300K`
