Theenthalpy of vapourisation of water at...

Theenthalpy of vapourisation of water at `100^(@)C" is 40.63 kJ mol"^(-1)`. The value `triangleE` for this proccss would be

A

`37.53 KJ mol^(-1)`

B

`39.08 KJ mol^(-1)`

C

`42.19 KJ mol^(-1)`

D

`43.73 KJ mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`H_(2)O_((l))rarr H_(2)O_((g))`
`Delta H= Delta E + Delta n_(g)RT`
`Delta E=40.63-1xx8.314xx10^(-3)xx373`
