Energy vs. Enthalpy

Postby Daisylookinland » Mon Jan 28, 2019 12:52 pm

Is there a difference between the enthalpy of a reaction and the energy required for the same reaction to take place?

Yes, enthalpy is the heat energy plus the work used to expand. The energy needed for the reaction to occur is the activation energy.

Enthalpy is the change in heat from the two stages of a reaction. The energy required for the reaction to take place is generally greater than the enthalpy, even for endothermic reactions.
