C3.2.2 - Reaction Profiles Flashcards
1
Q
What is a reaction profile?
A
A chart that shows the energy involved in a chemical reaction
2
Q
What is activation energy?
A
The minimum amount of energy needed to strat a reaction
3
Q
Why might some reactions not need activation energy?
A
The reactants already have enough energy to react
4
Q
If the energy change in a reaction profile is positive, what type of reaction is it?
A
Endothermic
5
Q
If the energy change in a reaction profile is negative, what type of reaction is it?
A
Exothermic
6
Q
If the reactants have more energy than the products, what type of reaction is it?
A
Exothermic
7
Q
If the products have more energy than the reactants, what type of reaction is it?
A
Endothermic
