![**Predicting the Sign of ΔS for a Given Reaction**
The image presents a chemical reaction for which you need to predict the sign of the change in entropy (ΔS).
**Reaction:**
\[ \text{C-Br} \quad \rightarrow \quad \text{C} = \text{C} + \text{HBr} \]
Here, a carbon-bromine compound reacts to form a carbon-carbon double bond (alkene) and hydrogen bromide (HBr).
**Options:**
1. Negative
2. No answer text provided.
3. No change
4. Positive
**Explanation of Reaction:**
In this reaction:
- On the left side, there is a single reactant molecule, the carbon-bromine (C-Br) compound.
- On the right side, there are two products: one molecule of alkene (carbon-carbon double bond) and one molecule of hydrogen bromide (HBr).
**Interpreting Entropy (ΔS):**
Entropy (S) is a measure of the disorder or randomness in a system:
- The formation of more products generally increases the entropy because more molecules usually mean more ways to arrange them and thereby more disorder/ randomness.
- Here, going from one reactant molecule to two product molecules suggests an increase in disorder.
Thus, the correct answer is likely to be **positive ΔS**, indicating an increase in entropy.
**Conclusion:**
Given the reaction and the options provided, you would predict the sign of ΔS to be positive. This reflects an increase in entropy as a result of the reaction producing more molecules.
**Quiz Question:**
Predict the sign of ΔS for the following reaction:
\[ \text{C-Br} \quad \rightarrow \quad \text{C} = \text{C} + \text{HBr} \]
