C2.5 Exothermic & Endothermic reactions Flashcards
1
Q
Which reaction takes energy in from the surroundings?
A
ENDOTHERMIC REACTIONS
INdothermic reactions
2
Q
What reaction transfers energy to the surroundings?
A
EXOTHERMIC REACTIONS
EXIT - thermic reactions
3
Q
How is the temperature affected in an endothermic reaction?
A
The reaction takes in heat energy and so makes the temperature cooler.
4
Q
What are examples of exothermic reactions?
A
- Combustion
- Neutralisation
- Oxidisation
5
Q
What are examples of endothermic reactions?
A
- Electrolysis
- Thermal decomposition
6
Q
What type of reactions are reversible reactions?
A
Reversible reactions will be exothermic in one direction and endothermic in the opposing direction
7
