A. lower than the freezing point of the solvent alone because higher temperature is required to accelerate solvent molecular motion enough to overcome obstructon by solute particles..
B. higher than the freezing point of the solvent alone because higher temperature is required to accelerate solvent molecular motion enough to overcome obstruction by solute particles.
C. lower than the freezing point of the solvent alone because lower temperature is required to accelerate solvent molecular motion enough to overcome obstruction by solute particles.
D. lower than the freezing point of the solvent alone because lower temperature is required to slow solvent molecular motion enough to overcome obstruction by solute particles.
E. None of these are true.
i think it's D, am i right
Is it too brash to ask what is the question?
To determine the correct answer, we need to understand the concept of freezing point depression. Freezing point depression occurs when the presence of solute particles lowers the freezing point of the solvent compared to its pure state.
When solute particles are dissolved in a solvent, they disrupt the crystal lattice formation during freezing, making it more difficult for the solvent molecules to form solid structures. As a result, a lower temperature is needed to freeze the solution.
Among the given options, the correct answer is indeed D. It states that the freezing point of the solution is lower than the freezing point of the solvent alone because a lower temperature is required to slow down the solvent molecular motion enough to overcome obstruction by solute particles.
In summary, the correct answer is D.
