How are activation energy and reaction rate most likely related? (1O A faster reaction rate results in lower activation energy.A faster reaction rate results in higher activation energy.

Higher activation energy results in slower reaction rate. Option D is correct
Activation energy is the energy required needed by compounds or molecules to undergo chemical reactions.
The activation energy of a reaction is related to the rate of reaction. They are both inversely related. In order words, as the activation energy becomes higher, the rate of reaction becomes slower.
