Ammonium nitrate, NH4NO3, is used in “cold packs”. Which statement best describes why the products are favored, when the solid is mixed with water?

Question

NH4NO3(s) → NH4+ (aq) + NO3- (aq)

A) Heat is transferred to the surroundings to lower the temperature and the entropy change is positive.
B)The kinetic energy of the products decreases and the entropy change is positive.
C)The enthalpy change is positive and the entropy change is negative.
D)The potential energy of the products is more negative and the entropy change is positive.

Answer 1

I would look at D
