Unit Learning Outcomes

1.

Understand enthalpy changes associated with exothermic and endothermic reactions.

Assessment Criteria

  • 1.1

    Interpret enthalpy profile diagrams for exothermic and endothermic reactions including the concept of activation energy, EA.

  • 1.2

    Define standard conditions and standard enthalpy changes of combustion, formation and reaction.

  • 1.3

    Calculate enthalpy changes of reaction from average bond enthalpy values or experimental data.

  • 1.4

    State Hess’ Law and use enthalpy cycles to indirectly determine enthalpy changes.


2.

Understand the factors that affect the rate of a chemical reaction.

Assessment Criteria

  • 2.1

    Apply the collision theory to explain the factors that affect the rate of a reaction.

  • 2.2

    Analyse the Maxwell Boltzmann distribution curve to explain the effect of temperature on the rate of a reaction.


3.

Be able to apply Le Chatelier’s principle to explain the effects of changes in conditions on a system in dynamic equilibrium.

Assessment Criteria

  • 3.1

    State Le Chatelier’s principle and apply it to explain the effects of changing conditions on the position of equilibrium.


4.

Understand the theory and reactions of acids and bases.

Assessment Criteria

  • 4.1

    Define acids and bases using the Bronsted-Lowry theory.

  • 4.2

    Explain how the pH scale is used to measure acidity and alkalinity.

  • 4.3

    Explain the reactions of acids with alkalis, a metal and a carbonate.


5.

Understand simple redox processes.

Assessment Criteria

  • 5.1

    Explain oxidation and reduction in terms of electron transfer and changes in oxidation state.
