If you increase the temperature in a reversible reaction, what happens?
|
The endothermic reaction will increase.
|
|
If you decrease the temperature in a reversible reaction, what happens?
|
The exothermic reaction will increase.
|
|
If you increase the pressure in a reversible reaction, what happens?
|
The high pressure will favour the reaction which produces less volume.
|
|
If you decrease the pressure in a reversible reaction, what happens?
|
The low pressure will favour the reaction which produces more volume.

200 Atmospheres.
|
|
What is the temperature used in the Haber Process?
|
450°C.
|
|
What is an exothermic reaction?
|
A reaction which gives out heat.
|
|
What is an endothermic reaction?
|
A reaction which takes in heat.
|
|
In an endothermic reaction, how does the temperature change?
|
The temperature decreases.
|
|
In an exothermic reaction, how does the temperature change?
|
The temperature increases.

|
Explain what is meant by the term isotope.
|
Isotopes are different atomic forms of the same element, which have the same number of protons but a different number of neutrons.
|
|
What types of elements bond ionically?
|
Non-metals and metals.
|
|
Why do ionic structures have high melting and boiling points?
|
Because they have very strong chemical bonds between all the ions in the giant structure.
|
|
Why do ionic structures conduct electricity when they are in solution?
|
Because when dissolved, the ions are separate and can carry the charge.
|
|
Why do ionic structures conduct electricity when they are molten?
|
Because the ions are free and they can carry the charge.
