Step 1: Understand the question and its context
The question asks us to identify the best description of activation energy from the given options. Activation energy is a concept in chemistry and physics, which refers to the minimum amount of energy required for a chemical reaction to occur.
Step 2: Eliminate incorrect options
Option A: The maximum amount of energy required to end a chemical reaction. This option can be eliminated because activation energy refers to the beginning of a reaction, not the end. Option D: The amount of energy released in an exothermic reaction. This option is also incorrect because activation energy is the energy required to start a reaction, not the energy released during the reaction.
Final Answer
The minimum amount of energy required to start a chemical reaction.
