The statement that best describes the activation energy on the graph below is the vertical difference between 1 and 2 (option B).
What is activation energy?
Activation energy is the energy required to initiate a reaction. For example, the flame from the fuse of a firecracker provides a small initial amount of energy, after which the explosive reaction proceeds by itself, releasing a considerably larger quantity of energy.
According to this question, a reaction proceeds from 1 to 3. The activation energy needed for the reaction to be initiated is the vertical line that extends to the peak of 2.
Therefore, it can be said that the statement that best describes the activation energy on the graph below is the vertical difference between 1 and 2.
