What is equilibrium
The rate of concentration of products is constant.
1 of 27
Why is the rate of reaction dependant on surface area?
Greater surface are to volume ratio. More area for collisions to occur, increasing frequency of collisions.
2 of 27
Why is the rate of reaction dependant on a catalyst?
Catalyst offers a reaction pathway with a lower activation energy. Particles need to collide with less minimum energy for the reaction to take place, increasing rate.
3 of 27
Why is the rate of reaction dependant on temperature?
Higher temp, faster the particles move, increasing frequency of collisions. particles also transfer more energy during each collision due to greater thermal energy stores.

What ion does zinc form?
Zn 2+
5 of 27
What's the nomenclature for the first ten carbon atoms?
meth, eth, prop, but, pent, hex, hept, oct, non, dec
6 of 27
What's a covalent bond?
Electrostatic attraction between positive nuclei and negative shared pair(s) of electrons.
7 of 27
What's an ionic bond?
Electrostatic attraction between metal cations and non-metal anions
8 of 27
What's a metallic bond?
Electrostatic attraction between positive metal ions and sea of delocalised, negatively charged electrons.
9 of 27
What is a reversible reaction?
Products can react with each other to form reactants. It can go both ways.
10 of 27
What is addition polymerisation?
Many monomers combine to form a polymer. Nothing is lost.
11 of 27
What is condensation polymerisation?
When a water molecule (H2O) is lost from the polymer.
12 of 27
What is a polymer
molecule that has a high average relative molecular mass and has many repeating units
13 of 27
Difference between addition and condensation polymerisation?
Condensation polymerisation for esters, diol and dicarboxylic functional groups and water molecule (H2O) is lost
14 of 27
What does activation energy mean?
The minimum energy that particles need to react. the minimum energy they transfer when they collide is known as the activation energy.
15 of 27
What the equation for bond energy?
Energy absorbed - Energy released.
16 of 27
What does a saturated molecule mean?
C-C single bonds Alkane lack of functional group very unreactive
17 of 27
What does an unsaturated molecule mean?
C=C Double bond Alkene functional group highly reactive
18 of 27
What type of atoms form simple covalent bonds?
non-metals
19 of 27
What's the formula for nitric acid?
HNO3
20 of 27
What's the formula for sulphuric acid acid?
H2SO4
21 of 27
What's a reversible reaction?
Products of a reaction react to produce their original reactants. It can go both ways.
22 of 27
What type of atoms form simple covalent bonds?
non-metals
23 of 27
Whats the nomenclature of chlorine?
Chloro
24 of 27
Whats the nomenclature of bromine?
Bromo
25 of 27
