Chemical Thermodynamics Question 37

Question: For the reaction $ H_2O(s) $ ⇌ $ H_2O(l) $ at $ 0^{o}C $ and normal pressure [KCET 2001]

Options:

A) $ \Delta H>T\Delta S $

B) $ \Delta H=T\Delta S $

C) $ \Delta H=\Delta G $

D) $ \Delta H<T\Delta S $

Show Answer

Answer:

Correct Answer: B

Solution:

$ H_2{O_{(g)}} $ ⇌ $ H_2{O_{(l)}} $ we know $ \Delta G=\Delta H-T\Delta S $ at equilibrium $ \Delta G=0 $ Therefore $ \Delta H=T\Delta S $ .
