Chemical Change
Definition
when a substance changes into a different substance changing identity of matter.
Term
What is needed for a chemical reaction to take place?
Definition
1. Activation energy 2. Correct alignment
Term
What do enzymes do?
Definition
They speed up the chemical reaction. because the have an active side, the lower activation energy.
