Activation energy Flashcards
(12 cards)
What is the activation energy of a chemical reaction?
energy required to break reactant bonds
What is the symbol
EA
Smaller activation
less energy needed
Large activation
more energy
Do all reactions initally absorb energy to break bonds?
Yes
Exothermic releases all true or false?
True
Which way does Endothermic reactions go, reactant to product?
Up
Which way does Exothermic reactions go reactant to product
Downwards
How does a successful reaction occur
reaction particles collide
right way with minimum amount of enregy
What is the collision theory
Particles must collide with correct orientation and suffienct energy
What is the law of conservation of mass?
Mass cannot be created nor destroyed, only re arranged
What is the law of conservation of Energy
total amount of energy in a closed system stays the same over time.
