Question

True statement about exothermic reactions:
1. The reactants of the reaction are more complex than the products.
2. The energy of the reactants is lower than the products.
3. The products of the reaction are more complex than the reactants.
4. The energy of the products is lower than that of other reactants.

Answer 1

The correct statement about exothermic reactions is:

4. The energy of the products is lower than that of the reactants.

In exothermic reactions, energy is released to the surroundings, resulting in products that have lower energy than the reactants. This is often observed as an increase in temperature in the surrounding environment.
