For the process H2O(l) (1 bar, 373 K) → H2O(S) (1 bar,373 K), the correct set of thermodynamic parameters isΔ

 

 


A) △G=0,△S=+ve

B) △G=0,△S=−ve

C) △G=+ve,△S=0

D) △G=−ve,△S=+ve

Answer:

Option A

Explanation:

Since liquid is passing into the gaseous phase so entropy will increase and at 373 K during the phase transformation it remains at equilibrium. So, ΔG = 0.
