HS-PS1-5: Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or
concentration of the reacting particles on the rate at which a reaction occurs. [Clarification Statement: Emphasis is on student
reasoning that focuses on the number and energy of collisions between molecules.] [Assessment Boundary: Assessment is limited to
simple reactions in which there are only two reactants; evidence from temperature, concentration, and rate data; and qualitative
relationships between rate and temperature.]
HS-PS1-6: Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of
products at equilibrium.* [Clarification Statement: Emphasis is on the application of Le Chatelier’s Principle and on refining designs
of chemical reaction systems, including descriptions of the connection between changes made at the macroscopic level and what
happens at the molecular level. Examples of designs could include different ways to increase product formation including adding
reactants or removing products.] [Assessment Boundary: Assessment is limited to specifying the change in only one variable at a
time. Assessment does not include calculating equilibrium constants and concentrations.]

Content Statements
Gas particles move independently and are
far apart relative to each other. The
behavior of gases can be explained by the
kinetic molecular theory. The kinetic
molecular theory can be used to explain the
relationship between pressure and volume,
volume and temperature, pressure and
temperature, and the number of particles in
a gas sample. There is a natural tendency
for a system to move in the direction of
disorder or entropy.
Heating increases the energy of the atoms
composing elements and the molecules or
ions composing compounds. As the kinetic
energy of the atoms, molecules, or ions
increases, the temperature of the matter
increases. Heating a pure solid increases
the vibrational energy of its atoms,
molecules, or ions. When the vibrational
energy of the molecules of a pure
substance becomes great enough, the solid
melts.
4. The change in
concentration or heat will
affect a reaction but it will
sooner return back to
equilibrium

Indicators
Use the kinetic molecular
theory to describe and

system at equilibrium will cause a shift in
the reaction to neutralize that change until
