Question

Choose the situation below that would result in a ΔH_solution near 0. A) When >> B) When > C) When < D) When is close to E) There isn't enough information to determine.

Quizplus · Accepted Answer

ΔH_solution represents the enthalpy change of solution (heat absorbed or released) when one mole of a substance is dissolved in a large amount of solvent. The closer the values of the two substances are, the closer to zero the ΔH_solution will be. Therefore, option D is the best choice as the two values given are close together, indicating a nearly zero enthalpy change of solution.
