SAT Subject Test Chemistry,10 edition

All of the statements are examples of colligative properties. Colligative properties are properties of
solutions that depend only on the number of solute particles present and not on the nature of those
particles. Examples of colligative properties are boiling point elevation, freezing point depression,
osmotic pressure, and vapor-pressure lowering. They are usually associated with dilute solutions.
Choice E is correct.

Type 3 Questions

These questions are also organized in sets, but center on an experiment, chart, graph, or other
experimental data presentation. They assess how well you apply science to unfamiliar situations.
Each question is independent of the others; in addition, these questions are typically found in the
latter part of the test. Most students find them to be the most difficult questions on the test.

Type 3 questions test your ability to identify a problem; evaluate experimental situations; suggest
hypotheses; interpret data such as graphs or mathematical expressions; make inferences and draw
conclusions; check the logical consistency of hypotheses based on your observations; convert
information to graphical form; apply mathematical relationships; and select the appropriate
procedure for further study.

Questions   10–13   are based   on  the following   equation:

N 2 (g) +   3H 2     (g) 2NH 3   (g)    ∆H  =   –30 kJ/mole

(A) I   only

(B) IV  only

(C) I   and IV  only

(D) II  and III only

(E) I,  II, III,    and IV

How will    the equilibrium of  the following   reaction    be  affected    if  the temperature is

increased?

10.

(A) It  will    be  shifted to  the right.

(B) It  will    be  shifted to  the left.
