C2 REVISION ­ CHAPTER 2 ­ STRUCTURE & PROPERTIES
IONIC COMPOUNDS
SIMPLE COVALENT MOLECULES GIANT METALLIC SUBSTANCES
What type of force holds the ions
How strong are the forces between Why can metals be bent and shaped?
together?
covalent molecules? [intermolecular
forces]
What are delocalised electrons?
Draw a giant ionic lattice:
How does this affect their melting
and boiling point Why do metals conduct electricity?
How strong are the forces between
atoms in a covalent bond?
[intramolecular bonds] How are polymers classified: What is nanoscience?
Why do ionic compounds have high Thermosetting:
melting and boiling points?
Thermosoftening:
Why can ionic compounds conduct
electricity when molten or
dissolved in water? GIANT COVALENT SUBSTANCES
KEY WORDS: ASSESSMENT:

C2 REVISION ­ CHAPTER 4 ­ RATES & ENERGY
What do we mean by `rate of reaction'? Explain the effect of temperature on the rate
Explain the effect of concentration on
the rate of reaction of reaction [think about: kinetic energy &
number of collisions]
What 4 factors affect the rate of a
reaction?
Draw diagrams to represent it? Draw diagrams to represent it:
What must happen for a reaction to
occur?
What is the smallest amount of energy
that must be overcome for a reaction to Low concn High concn Low temp High temp
occur?
How does surface area affect the rate of reaction?
What do catalysts do?
What happens to them during a reaction?
Explain exothermic reactions:
KEY WORDS: ASSESSMENT:
What energy changes are
involved in a reversible Collision theory
Explain endothermic reactions: reaction? Activation energy
Catalyst
Exothermic
Endothermic
Thermal decomposition…read more
