Question

During a chemical reaction, if the products have more chemical energy than the reactants,

• A. energy is released
• B. energy is absorbed
• C. no changes in energy
• D. depends

Answer 1

The correct option is B

energy is absorbed

Because energy is conserved in a chemical reaction i.e., the energy on both reactants and products side is equal, if, during a chemical reaction, the products formed have more chemical energy than the reactants, energy is absorbed on the reactants side. Or vice versa.
