At `25^(@)C, Delta G^(0)` for the process `H_(2)O_((l)) hArr H_(2) O_((g))` is 8.6kJ. The vapour pressure of water at this temperature, is nearly

A

24 torr

B

285 torr

C

32.17 torr

D

100 torr

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta G^(0) = -RT ln K_(P) = - RT l n (P_(H_(2)O))`
`rArr P_(H_(2)O) = 0.03 atm = 24` torr
