Select from the frequently asked questions below
- An endothermic reaction is a chemical reaction in which more energy is needed to break bonds in the reactants than is released when new bonds form in the products.
- In photosynthesis, plants make the simple sugar glucose (C6H12O6) from carbon dioxide (CO2) and water (H2O).
- They also release oxygen (O2) in the process.
- The energy needed for photosynthesis comes from light.
- Without light energy, photosynthesis cannot occur.
- The drop in temperature may be great enough to cause liquids to freeze.
Why is the temperature of the products likely to be lower than the temperature of the reactants in an endothermic reaction?
