Chemistry: Dynamic Equilibrium and Physical Properties Quiz

Gas Solubility

• According to Henry's law, the mass of a gas dissolved in a solvent is directly proportional to the partial pressure of the gas above the solvent.

Solution Concentration

• In a saturated solution, the concentration of solute depends primarily on the temperature.

Chemical Reactions

• The reaction quotient (Q) measures the ratio of product concentrations to reactant concentrations at any time during a chemical reaction.

Electrolytes

• Strong electrolytes dissociate completely into ions in an aqueous solution.

Buffer Solutions

• A buffer solution is a solution that resists changes in pH when an acid or base is added.

Solution Saturation

• A solution is said to be unsaturated if it can still dissolve more solute.

Equilibria

• According to the characteristics of equilibria involving physical processes, the temperature remains constant during dissolution of gases in liquids.

Phase Equilibrium

• Solid-to-liquid equilibrium occurs at the melting point of a substance.
• Dynamic equilibrium is the stage of the solution where the rates of dissolution and crystallization are equal.

Physical Equilibrium

• Equilibrium between two different physical states means that the rates of forward and reverse physical processes are equal.
• Dynamic equilibrium means that the rates of forward and reverse reactions are equal, but not zero.

Buffer Solution pH

• Dilution with water does not affect the pH of a buffer solution.

Boiling Point

• The boiling point of a liquid depends on the intermolecular forces between its molecules.

Dynamic Equilibrium

• In dynamic equilibrium, the concentrations of reactants and products do not change over time, but the rates of forward and reverse reactions are equal.
