The ways in which chemists can help food production,
including providing extra nutrients, controlling soil pH and controlling
pests (the Storyline in general). |
 |
| 2 |
The effect of temperature on the rate constant of the reaction. |
|
| 3 |
The redox reactions involved in the interconversion of the following
species in the nitrogen cycle: nitrogen gas, nitrate(V) ion, nitrate(III)
ion, ammonium ion, dinitrogen oxide (N2O), nitrogen monoxide
(NO), nitrogen dioxide (NO2) (Storyline AA3; Activity
AA3.2). |

An outline of the manufacture of ammonia by the Haber Process,
including essential conditions (Storyline AA3). |
|
| 5 |
Why the conditions in the Haber Process are chosen, including the
effect the conditions have on the position of equilibrium and on the
rate of reaction (Storyline AA3). |
|
| 6 |
The expression for the equilibrium constant, Kp, for
reactions involving gases (in terms of partial pressures). |
|
| 7 |
How values of Kp, together with given data on partial
pressures, are used to carry out calculations concerning the composition
of equilibrium mixtures. |
|
| 8 |
The trends in reactions of the elements, and the properties of their
compounds, across a period in terms of structure and bonding, including:
the reactions of the elements with oxygen, chlorine and water; the
acid-base character of oxides; the behaviour of chlorides towards water. |
|
| 9 |
The relationship between the structure and bonding of a substance and
its properties. |
|
| 10 |
The partition equilibrium that occurs when a solute is distributed
between two immiscible solvents. |
|

The design of pesticides that combine maximum efficacy with minimum
environmental damage (Storyline AA4). |
