Activation energy is:
I) the minimum kinetic energy required for each molecule in a collision to produce a reaction.
II) the minimum total kinetic energy required for the molecules in a collision to produce a reaction.
III) a factor in determining the rate of a reaction.
IV) high for fast reactions.
