Question

Hello, I need help solving the 3 parts of this question.

Part - Factors affecting the dissolution process The rate at which a solute dissolves in a solvent depends on the kinetic energy of the soluton, theme of contact and the surface area of contact between the solute and the solvent particles. Both endothermic and exothermic dissolution processes will respond similarly to each factor, however the charge may be more pronounced depending on the thermodynamic penters of the reaction. As the kinetic energy, tme of contact and surface area of contact between the solute and the solvent particles increase the rate at which the solute undergoes dissolution in a solvent increases. Similarly, as the kinetic energy, time of contact and surface area of contact between the solute and the so vent particles de base, the rate at which the sole undergoes d outon in a solvent doces The dissolution process can be stored by varying the parameters, such as by increasing or decreasing the comperature or by reducing the particle size of the soluto. Consider the preparation of a NaCl sa solution using course crystals of NaClin an tired container at room temperature. Classify the following condtions based on the change in the rate of dissolution of NaCl in water compared to the initial preparation the dissolution process is endothermic Drag the appropriate tems to their respective bins.

No on based NaCl at lave and the Faster dissolution process Slower dissolution process

Answer 1

1. faster dissolution :

NaCl is added to water and the mixture is stirred

finely powdered NaCl is added to water

NaCl is added and the mixture is heated

slower dissolution:

NaCl is added and the solution is cooled

a large piece of NaCl is added to water

2. NaCl crystals are added in water, Cl^- ions are attracted by water molecules, na⁺ ions are attracted by water moplecules, NaCl solution is formed

3. Propanol forms a solution inheptane

table salt dissolves in water

Carbon dioxid eis more soluble at higher partial pressure

Copper sulfate is soluble in water
