Which of the following statements is true about exothermic reactions?
- A They release heat to the surroundings.
- B They absorb heat from the surroundings.
- C They have a positive change in enthalpy.
- D They involve only solids and liquids.
That's Correct!
It's Wrong!
The true statement about exothermic reactions is:They release heat to the surroundings.Exothermic reactions are characterized by a release of energy in the form of heat to the surroundings. This release of heat is often accompanied by an increase in temperature of the surroundings. The change in enthalpy ΔH for exothermic reactions is negative, indicating a decrease in the enthalpy of the system as heat is given off. Exothermic reactions can involve various states of matter, including gases, liquids, and solids.
