Question

1. chemical reactions that absorb more energy than they release are called (1 point)

● catalyzed
● endothermic
● activated
● exothermic

Explanation:

Endothermic reactions absorb more energy (heat) than they release. Catalyzed reactions involve a catalyst, exothermic release more energy, and activated refers to a reaction state. So the correct term is endothermic.

Answer:

B. Endothermic (assuming the options are labeled with B for endothermic as per typical multiple - choice setups; adjust label if needed based on actual option numbering)
