Answer:
d. delta H is positive, and delta S is positive
Explanation:
The process of dissolution of NH4Cl is:
NH4Cl(s) → NH4+(aq) + Cl-(aq)
As the solution is cooled, the process is absorbing energy, that means ΔH > 0. (ΔH < 0 when the heat is released).
As there are produced 2 ions from 1 solid molecule, the disorder is increasing and ΔS > 0
The right answer is:
<h3>d. delta H is positive, and delta S is positive</h3>
The molar concentration of a solution, usually expressed as the number of moles of solute per liter of solution.
