Define activation energy.
Define activation energy.
Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.
How does activation energy affect the rate of a chemical reaction?
How does activation energy affect the rate of a chemical reaction?
Activation energy determines the rate of a chemical reaction; higher activation energy means the reaction is slower.
Explain why some reactions have high activation energies.
Explain why some reactions have high activation energies.
Reactions with high activation energies have more complex or unstable reactants that require more energy to initiate the reaction.
What happens to a chemical reaction if the activation energy is lowered?
What happens to a chemical reaction if the activation energy is lowered?
