Which image shows an exothermic reaction?

• 
• 

Which of the following best describes this image?

• Reactants have more energy than the products, which means energy is being released. This is an exothermic reaction.

• Reactants have less energy than the products, which shows energy is being absorbed. This is an endothermic reaction
