Can you explain the answer of this question below:A reaction is not fe...
Explanation:

Given Conditions:
- H is the enthalpy change (heat transfer) of the reaction.
- S is the entropy change (disorder) of the reaction.

Explanation of Option B:
- When H is positive and S is negative, it means that the reaction absorbs heat from the surroundings (endothermic) and the disorder decreases during the reaction.
- In this scenario, the reaction is not feasible because although heat is being absorbed, the decrease in disorder counteracts the effect of heat absorption, making the reaction unfavorable.
- For a reaction to be feasible, both heat transfer and entropy change should be in the same direction, either both positive or both negative.
- Therefore, the correct answer is option B, as it represents a combination where the enthalpy change is positive (heat absorbed) but the entropy change is negative (disorder decreases), making the reaction non-feasible.

Conclusion:
- Understanding the relationship between enthalpy and entropy changes is crucial in determining the feasibility of a reaction.
- A positive enthalpy change combined with a negative entropy change results in a non-feasible reaction, as seen in option B.
