Question

How do you know if a Reaction Absorbs or Release Energy?

Answer 1

1. To know, if a reaction absorbs or releases energy, can be easily determined using the enthalpy of the reaction.
2. If the enthalpy of a reaction is positive, then it represents that the energy is absorbed during the reaction.
3. If the enthalpy of a reaction is negative, then it represents that the energy is released during the reaction.
