Energy Profile Diagrams Flashcards
1
Q
what is energy also known as
A
enthalpy
2
Q
What does an exothermic reaction look like on an energy profile graph
A
reactants start and a curve for activation energy but the product finish lower then the reactants
Energy has been lost
3
Q
what does an endothermic reaction look like on an energy profile graph
A
reactants then activation energy curve which has product finish higher then reactants at start
energy has been gained
4
Q
what is activation energy
A
the minimum amount of energy
that must be supplied for a reaction to occur
5
Q
what is enthalpy change represented with
A
delta H
