5.5 Energy Changes Flashcards
1
Q
Activation energy
A
The minimum amount of energy for particles to collide with in order for a successful reaction to occur
2
Q
Endothermic reaction
A
An endothermic reaction is one that takes in energy from the
surroundings so the temperature of the surroundings decreases
3
Q
Exothermic reaction
A
An exothermic reaction is one that transfers energy to the
surroundings so the temperature of the surroundings increases
4
Q
Reaction profile
A
Reaction profiles can be used to show the relative energies of reactants and products, the activation energy and the overall energy change of a reaction
