What are the signs of the entropy charge (+ or - ) in the following cases.
I: A liquid crystallizes into a solid
II : Temperature of a crystalline solid is raised from 0 K to 115 K
III : 
(s) 
(s) 
(g) 
IV : 
I II III IV
Text Solution
Verified by ExpertsThe correct answer is:
A
When liquid crystallizes into solid, its entropy decreases.
If temperature increases, entropy increases.
If gaseous moles increases after reaction, then entropy increases.
molecule breaks into 2 gaseous H -atom, so entropy increases.
So, signs of entropy change are
