Energy Transfer in Reactions Flashcards
1
Q
What is an exothermic reaction?
A
A reaction that transfers energy to the surroundings, usually in the form of heat and is usually shown by a rise in temperature.
2
Q
What reactions are also exothermic?
A
1) neutralisation (alkali + acid)
2) combustion
3) oxidation
3
Q
What is an endothermic reaction?
A
A reaction where heat is taken in from the surroundings in heat, and causes a fall in temperature.
4
Q
What is an example of an endothermic reaction?
A
Thermal decomposition.
5
Q
What type of reactions can be endothermic and exothermic?
A
Reversible reactions (endothermic one way and exothermic the other).
