Lana Lyons · Answer 1

B) High activation energy barriers result in low rates

Kayley Cabrera · Answer 2

Answer: option B) High activation energy barriers result in low rates.

Justification:

1) Activation energy is the minimum amount of energy required for the reagents to form the activated complex and the reaction start.

2) Then the activation energy influences directly of the rate of reaction. A high activation energy means that few collisions will have the needed energy to form the activated complex and, consequently, the rate of reaction will be low.
