For the reaction H 2 O ( s ) ⇋ H 2 O ( l ) at 0°C and normal pressure Options: A . &nbsp△H > T△S B . &nbsp△H = T△S C . &nbsp△H = △G D . &nbsp△H

Answer: Option B : B Let's look at the reaction. H 2 O ( s ) ⇋ H 2 O ( l ) at 0 ∘ C It will be in equilibrium at 0 ∘ C Now, At equilibrium △ G = 0 & △ G = △ H - T △ S ⇒ △ H - T △ S = 0 ⇒ △ H = T △ S

For the reaction H2O(s)⇋H2O(l) at 0°C and normal pressure

Question

For the reaction

H_{2} O (s) ⇋ H_{2} O (l)

at 0°C and normal pressure

Options:

A . △H > T△S

B . △H = T△S

C . △H = △G

D . △H < T△S

Answer: Option B
:
B
Let's look at the reaction.

H_{2} O (s) ⇋ H_{2} O (l)

0^{\circ} C

It will be in equilibrium at

0^{\circ} C

Now, At equilibrium

△

G = 0
&

△

G =

△

H - T

△

\Rightarrow △

H - T

△

S = 0

\Rightarrow △ H = T △ S
