Unit 1 · 7 skills

From Kinetics to Equilibrium

Reaction kinetics

Chemical equilibrium

The official wording · 7 outcomes
1.1
Describe collision theory and its connection to factors involved in altering reaction rates
1.2
Identify and discuss the properties and factors which affect reaction rate
1.3
Sketch and interpret potential energy diagrams for chemical reactions
1.4
Describe a reaction mechanism and a catalyst's role in a chemical reaction
1.5
Define the concept of dynamic equilibrium as it pertains to reversible chemical reactions
1.6
Define the concept of equilibrium constant expression as it pertains to chemical systems
1.7
Explain how different factors affect chemical equilibrium

Key ideas

  1. Reactions occur when particles collide with enough energy and correct orientation.

  2. A reversible reaction proceeds in both directions.

  3. Only collisions above the activation energy are effective.

  4. At equilibrium, forward and reverse rates are equal.

  5. Raising temperature, concentration, or surface area increases effective collisions.

Watch out for

  • That every collision leads to a reaction.
  • That equilibrium means the reaction stops.
  • That concentration changes the activation energy (it changes collision frequency).

Unit 2 · 8 skills

Acids and Bases

Acid-base definitions and strength

Indicators, Le Chatelier, and titration

The official wording · 8 outcomes
2.1
Describe various acid-base definitions up to and including the
2.2
Compare strong and weak acids and bases using the concept of equilibrium
2.3
Predict products of acid-base reactions
2.4
Calculate the pH of an acid or a base given its concentration, and vice versa
2.5
Compare strong and weak acids and bases using the concept of equilibrium
2.6
Explain how acid-base indicators function
2.7
Describe the interactions between
2.8
Determine the concentration of an acid or base solution using stoichiometry

Key ideas

  1. Arrhenius: acids release H+, bases release OH- in water.

  2. Indicators are weak acids/bases whose two forms have different colours.

  3. Bronsted-Lowry: acids are proton donors, bases are proton acceptors.

  4. The colour depends on pH via the indicator's own equilibrium.

  5. Conjugate acid-base pairs differ by one proton.

Watch out for

  • That only substances with OH can be bases.
  • That an indicator changes at exactly pH 7 for every titration.
  • That the Arrhenius and Bronsted-Lowry definitions contradict rather than extend each other.

Unit 3 · 12 skills

Thermochemistry

Heat, energy, and enthalpy

Measuring and calculating reaction energy

The official wording · 12 outcomes
3.1
Explain temperature and heat using the concept of kinetic energy and the particle model of matter
3.2
Distinguish between a system and surroundings and the relationship of each to the universe
3.3
Define specific heat
3.4
Calculate and compare the energy involved in changes of temperature
3.5
Define endothermic reaction, exothermic reaction, enthalpy, bond energy, heat of reaction, and molar enthalpy
3.6
Illustrate changes in energy of various chemical reactions, using potential energy diagrams
3.7
Calculate and compare the energy involved in changes of state and temperature
3.8
Calculate and compare the energy involved in chemical reactions
3.9
Determine experimentally the changes in energy of various chemical reactions
3.10
Compare the molar enthalpies of several combustion reactions involving organic compounds
3.11
Write and balance thermochemical equations including the combustion reactions of alkanes
3.12
Calculate the changes in energy of various chemical reactions using bond energy, heats of formation, and Hess's law

Key ideas

  1. Temperature measures the average kinetic energy of particles.

  2. Heating within a phase uses q = mc(delta)T.

  3. Heat is energy transferred due to a temperature difference.

  4. Changing phase uses latent heat (q = mL); temperature stays constant.

  5. Heat flows from hotter to colder until thermal equilibrium.

Watch out for

  • That temperature and heat are the same thing.
  • That temperature rises during a phase change.
  • That a larger object is always at a higher temperature.

Unit 4 · 9 skills

Electrochemistry

Redox reactions and half-reactions

Electrochemical cells and applications

The official wording · 9 outcomes
4.1
Define oxidation and reduction experimentally and theoretically
4.2
Compare oxidation-reduction reactions with other kinds of reactions
4.3
Write and balance half-reactions and net reactions for redox equations
4.4
Illustrate and label the parts of electrochemical cells and explain how they work
4.5
Compare galvanic and electrolytic cells in terms of energy efficiency, electron flow/transfer, and chemical change
4.6
Predict whether oxidation-reduction reactions are spontaneous based on their reduction potentials
4.7
Predict the voltage of various electrochemical cells
4.8
Explain the processes of electrolysis and electroplating
4.9
Explain how electrical energy is produced in a hydrogen fuel cell

Key ideas

  1. Oxidation is loss of electrons; reduction is gain (OIL RIG).

  2. A cell has two electrodes (anode, cathode) in electrolyte, linked by a wire and salt bridge.

  3. Oxidation number increases on oxidation, decreases on reduction.

  4. Oxidation happens at the anode; reduction at the cathode.

  5. Redox reactions always pair an oxidation with a reduction.

Watch out for

  • That oxidation must involve oxygen.
  • That electrons flow through the salt bridge.
  • That a substance can be oxidized without something else being reduced.
