It is important for scientists to know how much energy is given off or absorbed in a chemical reaction. Which options below would indicate an exothermic reaction?
mr001-1.jpgH = –
mr001-2.jpgH = +
Energy is considered a reactant in the reaction: A + B + energy mr001-3.jpg C + D
Energy is considered a product in the reaction: A + B mr001-4.jpg C + D + energy

The exothermic choices are:
- ΔH = – (negative enthalpy change)
- Energy is a product: A + B → C + D + energy
- Energy is released in the reaction
(The other options—ΔH = +, energy as a reactant, and energy absorbed—describe endothermic reactions.)
- ΔH = – (negative enthalpy change)
- Energy is a product: A + B → C + D + energy
- Energy is released in the reaction
(The other options—ΔH = +, energy as a reactant, and energy absorbed—describe endothermic reactions.)
