Observe the following reactions
I. \(\quad \mathrm{CaCO}_3(\mathrm{~s}) \rightarrow \mathrm{CaO}(\mathrm{s})+\mathrm{CO}_2(\mathrm{~g})\)
II. \(\quad \mathrm{Cl}_2(\mathrm{~g}) \rightarrow 2 \mathrm{Cl}(\mathrm{g})\)
III. \(\mathrm{H}_2 \mathrm{O}(1) \rightarrow \mathrm{H}_2 \mathrm{O}(\mathrm{s})\)
Identify the reactions in which entropy increases
- A I, II, III
- B I, II Only
- C I, III Only
- D II, III Only
Answer & Solution
Correct Answer
(B) I, II Only
Step-by-step Solution
Detailed explanation
When the number of gaseous atom increases entropy is increases. So in reaction I and II gaseous molecule produced so entropy increase.
