The enthalpy change for the transition of liquid water to steam is 41

1.	The enthalpy change for the transition of liquid water to steam is 41 kj/mol at 100°c and 1 atmpressure calculate entropy change for the process.
Answer» Entropy change of vaporisation ∆S_v = ∆Hv /T ∆H_v = 41 x 10³ J , T= 373 K So S_v = (41 x 10³)/373 = 109.92 JK^-1mol^-1

The enthalpy change for the transition of liquid water to steam is 41 kj/mol at 100°c and 1 atmpressure calculate entropy change for the process.

Answer»

Entropy change of vaporisation

∆S_v = ∆Hv /T

∆H_v = 41 x 10³ J , T= 373 K

So S_v = (41 x 10³)/373 = 109.92 JK^-1mol^-1
