Part A Any reaction that absorbs 150 kcal of energy can be classilied as \( \begin{array}{l}\text { O endothermic } \\ \text { O exidation } \\ \text { exothermic } \\ \text { Submit Aecouest Answer }\end{array} \)

Any reaction that absorbs energy, such as 150 kcal, is classified as endothermic. Endothermic reactions require heat to be added in order to proceed, which distinguishes them from exothermic reactions that release heat. In the context of real-world scenarios, think of endothermic processes like photosynthesis, where plants absorb sunlight (energy) to convert carbon dioxide and water into glucose and oxygen. It's like a solar-powered kitchen experiment where energy is stored for later use!
