Question

Shown are two graphs.  One gives the change in freezing point as a solute is added to Naphthalene and the other shows the change in freezing point as solute is added to Biphenyl. Given these two graphs, which of the following statements are justified?

Solutes have the same effect on the freezing point of both biphenyl and naphthalene.

The slope for the trend line is different for the two graphs.

There is not enough information given in these graphs to make useful interpretations.

The effect of addition of solute is different for the two different solvents.

The addition of solute has a larger effect on the freezing point of biphenyl that on the freezing point of naphthalene.

The addition of solute has a smaller effect on the freezing point of biphenyl that on the freezing point of naphthalene.

a.

Solutes have the same effect on the freezing point of both biphenyl and naphthalene.

b.

The slope for the trend line is different for the two graphs.

c.

There is not enough information given in these graphs to make useful interpretations.

d.

The effect of addition of solute is different for the two different solvents.

e.

The addition of solute has a larger effect on the freezing point of biphenyl that on the freezing point of naphthalene.

f.

The addition of solute has a smaller effect on the freezing point of biphenyl that on the freezing point of naphthalene.

Shown are two graphs. One gives the change in freezing point as a solute is added to Naphthalene and the other shows the change in freezing point as solute is added to Biphenyl. Given these two graphs, which of the following statements are justified?

Explanation / Answer

The addition of solute has a larger effect on the freezing point of biphenyl that on the freezing point of naphthalene.

e.

The addition of solute has a larger effect on the freezing point of biphenyl that on the freezing point of naphthalene.
