Given the balanced equation:
KNO3 (s) + 34.89 kJ H20, K+ (aq) + NO3 - (aq)
Which statement best describes this process?

A) It is endothermic and entropy increases.

B) It is endothermic and entropy decreases.

C) It is exothermic and entropy increases.

D) It is exothermic and entropy decreases.

Respuesta :

B)it is endothermic and entropy decreases

[tex]KNO3 (s)[/tex]  → [tex]K+ (aq) + NO_3^- (aq)[/tex] is an endothermic reaction and entropy decreasing.

What is an endothermic reaction?

An endothermic reaction is any chemical reaction that absorbs heat from its environment.

This reaction  [tex]KNO3 (s)[/tex]  → [tex]K+ (aq) + NO_3^- (aq)[/tex] is absorbing heat from the surrounding. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).

It will lower the entropy of the surroundings by absorbing energy. In doing so the surroundings will lose energy, and randomness is decreased. These reactions are not spontaneous.

Hence, option B is correct.
