What type of energy change is associated with exothermic reactions?

Options

  1. AAn increase in energy.
  2. BA decrease in energy.
  3. CNo change in energy.
  4. DAn increase in potential energy.

Correct answer

B. A decrease in energy.

Step-by-step solution

Exothermic reactions are characterized by a decrease in energy (enthalpy), as they release heat to the surroundings.
