SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

Kinetic Theory cont’d

Students should be able to:

5.3. 11.5 state Boyle’s law and Include graphical
Charles’ law; representations.

5.4. 11.6 perform calculations using: Calculations involving the
use of Van der Waals
(a) Boyle's law; equation of state are not

(b) Charles' law; and, required.

(c) the ideal gas Include calculations of
equation (pV = nRT); relative molar mass.
and,

5.5. 11.7 explain the following:

(a) the liquid state;

(b) melting; and,

(c) vaporisation.

6. Energetics

Students should be able to:

6.1. state that chemical Note that bond making is an
reactions take place exothermic process, that is:
through energy changes ΔH - ve
(usually in the form of heat) while bond breaking is an
associated with the endothermic process, that is:
breaking and making of ΔH + ve.
bonds;

6.2. 11.8 state that energy changes
occur in chemical reactions
associated with the making
and breaking of bonds;

6.3. 11.9 explain the differences
between exothermic and
endothermic reactions
using energy profile
diagrams;
