Consider a one step reaction. Which of the following does not describe the activation energy of the process?


The minimum amount of energy needed for a reaction to occur


The energy difference between the starting point and the transition state


The energy required to distort or break bonds in the reactants

To determine which statement does not describe the activation energy of a one-step reaction, let's break down each option and analyze its accuracy:

1. The minimum amount of energy needed for a reaction to occur: This statement accurately describes the activation energy. It represents the minimum energy required for the reaction to proceed, meaning that without reaching this energy threshold, the reaction will not take place.

2. The energy difference between the starting point and the transition state: This statement also accurately describes the activation energy. The transition state refers to an intermediate state between the reactants and products. The energy difference between the starting point (reactants) and the transition state represents the activation energy required for the reaction.

3. The energy required to distort or break bonds in the reactants: This statement accurately describes the activation energy as well. During a reaction, existing bonds in the reactants need to be distorted or broken before new bonds can form in the products. This requires input of energy, which is represented by the activation energy.

Therefore, all three statements accurately describe the activation energy of a one-step reaction.
