Chapter 17, Problem 87A

Interpretation Introduction

Interpretation:

The reason due to which smelling salts work differently in different temperature conditions needs to be explained.

Concept introduction:

An endothermic reaction proceeds faster at high temperatures (Le Chatelier principle)

Answer to Problem 87A

No, smelling salts would not work as well in winter days as they do in warm summer days because its decomposition is endothermic so reverse reaction will be favored at lower temperatures.

Explanation of Solution

According to Le Chatelier principle, in an endothermic reaction, the reduction of system temperature will shift the equilibrium to the left which will favor the backward reaction therefore the decomposition of smelling salts will slow down in winter and it will not work well.

Conclusion

Smelling salts will not work well in a cold winter day due to the decomposition reaction being endothermic.
