Suppose chemists in a lab are trying to release as much energy as possible from a chemical reaction. Which of the following options best represents a valid idea that will allow them to achieve their goal?

• The chemists increase the temperature, which leads to more molecules forming bonds.

• The chemists increase the amount of space where the reaction occurs, which leads to more molecules colliding and forming bonds.

• The chemists increase the stability of the bonds in molecules, which makes it harder to release energy.

• The chemists decrease the stability of bonds in molecules, which makes it easier for energy to be released.
