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.
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.
Calculate the amount of energy required to break the bonds in one mole of NH4
To determine the answer to this question, we need to understand the concept of exothermic reactions and the energy changes associated with them.
An exothermic reaction is a chemical reaction that releases heat or energy to the surroundings. In such reactions, the energy required to break the attractions among the solute particles and among the solvent particles can be compared to the energy released as attractions form between solute and solvent particles.
In an exothermic reaction, the energy released as attractions form between solute and solvent particles is greater than the energy required to break the attractions among the solute particles and among the solvent particles. This is because the net energy change of an exothermic reaction is negative, indicating that energy is being released.
Therefore, the correct answer to the question is:
A) greater than the energy released as attractions form between solute and solvent particles.
To solve this question, you need to have an understanding of exothermic reactions and the energy changes involved. Reading a chemistry textbook or consulting reliable online resources can help you gain a more comprehensive understanding of this topic.
