Question

In an exothermic reaction, the amount of energy required to break the attractions among the solute particles and among the solvent particles is

A) greater than the energy released as attractions form between solute and solvent particles.
B) less than the energy released as attractions form between solute and solvent particles.
C) equal to the energy released as attractions form between solute and solvent particles.
D) equal to the heat of solution.

Answer 1

c is the best answer. If I were the test giver, I would throw out this question.

The problem in the question is the word Exothermic reaction is that the answers say as attractions form.

In the breaking of the attractions, it does not occur "as attractions form". If that were occuring, it would be equilibrium, and not exothermic. Maybe the comma after reaction should not have been there, it changes the meaning.

Answer 2

nope

Answer 3

Calculate the amount of energy required to break the bonds in one mole of NH4
