- A chemical reactions occurs only when?
- molecules with suficient kinetic energy collide with each other.
- Activation Energy is
- The minimum energy reactants must have to start a chemical reaction.
- Activation energy is needed to change
- ATP to ADP.
- Catalyst
- Are substances that increase the rate of chemical reactions without being permanently changed or depleted.
- Enzymes are
- Protein catalysts, million time faster. Enzymes increases the rate of chemical reaction by lowering the activation energy necessary for reaction to begin.
- Heat Energy
- Is the energy that flows between objects that are at different temperature.
- Kinetic Energy
- When a moving object comes to rest, its kinetic energy is converted into heat energy by frition.
- Temperature
- Is a measure of how hot or cold a substance is relative to another.
