Q: What kind of reactions absorb energy from their surroundings as they occur?


Read this paragraph and choose the correct option from the provided answers:

Endothermic reactions absorb energy from the surroundings as the reaction occurs. When 1 mol of calcium carbonate decomposes into 1 mol of calcium oxide and 1 mol of carbon dioxide, 177.8 kJ of heat is absorbed. The process is shown visually in Figure above (B). The thermochemical reaction is shown below.

 Choices:

- exothermic

- hydrostatic

- autotrophic

- endothermic


A:
endothermic
