Reaction that takes in energy from the surroundings
3
Q
What is a catalyst
A
A chemical that increases rate of reaction
4
Q
What is activation energy?
A
Minimum amount of energy to start a reaction
5
Q
What happens in a chemical change?
A
In a chemical change, reactant bonds are broken and new substances are made as product bonds are formed.
6
Q
What happens when bonds break?
A
Breaking bonds, takes in energy from the surroundings and this is an endothermic change.
7
Q
What happens when bonds are made?
A
Making bonds release energy to the surroundings and this ia an exothermic change.
