Options:

  1. They absorb heat.
  2. They release heat.
  3. They have a positive ΔH.
  4. They are always spontaneous.

Correct Answer: They release heat.

Exam Year: 2022

Solution: 

Exothermic reactions release heat to the surroundings, resulting in a negative change in enthalpy (ΔH < 0).

Questions & Step-by-Step Solutions

Which of the following is true about exothermic reactions? (2022)
  • Step 1: Understand what an exothermic reaction is. It is a type of chemical reaction that releases heat.
  • Step 2: Recognize that when heat is released, the temperature of the surroundings increases.
  • Step 3: Learn about enthalpy, which is a measure of heat content in a system.
  • Step 4: In exothermic reactions, the change in enthalpy (ΔH) is negative, meaning the system loses heat.
  • Step 5: Conclude that exothermic reactions are characterized by the release of heat and a negative ΔH.
