Answer the following question given this paragraph: All chemical reactions need energy to get started. Even reactions that release energy need a boost of energy in order to begin. The energy needed to start a chemical reaction is called activation energy . Activation energy is like the push a child needs to start going down a playground slide. The push gives the child enough energy to start moving, but once she starts, she keeps moving without being pushed again. Activation energy is illustrated in Figure below . Q: What is the amount of energy required to begin a chemical reaction known as? Choices: - decomposition energy - reaction energy - positive energy - activation energy A:
The answer to this question is:
activation energy
