Enthalpy vs. Energy

Postby Helen Struble 2F » Sun Jan 26, 2020 4:06 pm

What exactly is the difference between enthalpy of a reaction and the energy of the reaction, or is enthalpy just a more specific term for the energy of a reaction?

Enthalpy is equal to the system's internal energy plus the product of its pressure and volume. In a closed system, the heat absorbed or released equals the change in enthalpy.

Energy is the ability to do work, and is usually expressed in joules. Enthalpy is more specific - the ability of a certain material to do work, usually expressed in joules per mass unit (gram, kg, etc).
