Exo and Endo Flashcards
1
Q
What is exothermic reaction
A
a reaction where by energy is transferred into the surroundings
2
Q
What is an endothermic reaction
A
a reaction where by energy is taken in by the reaction
3
Q
How can you tell from a reaction profile whether a reaction is endo or extho thermic
A
In exothermic, the end energy is less than the start, because energy, is released,
In endo, the end energy is more because energy is taken in
4
Q
Describe energy change (Bond breaking and bond making
A
Bonds are broken when energy increases (reactants) and bonds are formed when energy is given out (Products)
In exo more is given out then taken in. Vice versa for Endo.
