Energy Level Diagrams - chem Flashcards
1
Q
What does endothermic mean?
A
When heat is taken in from the surroundings
2
Q
What happens during an exothermic reaction?
A
Energy is released when forming new bonds is more than energy needed to break the reactants bonds
3
Q
What happens during an endothermic reaction?
A
Energy required to break the reactants bonds and so energy is taken from the surroundings
4
