What is a common characteristic of spontaneous exothermic reactions according to the second law of thermodynamics?

Options

  1. AThey release heat to the surroundings.
  2. BThey decrease the disorder of the surroundings.
  3. CThey have a negative overall entropy change.
  4. DThey are rare in nature.

Correct answer

A. They release heat to the surroundings.

Step-by-step solution

According to the second law of thermodynamics, spontaneous exothermic reactions release heat to the surroundings, which increases the disorder of the surroundings.
