I was doing a True/False exercise and come across this one:
The enthalpy change measures the energy of the reaction when it occurs in a closed recipient with rigid walls.
With the knowledge I have, I think the energy of the reaction does not depend on the caracteristics of the recipient. What happens is that if it occurs in an open recipient the energy will disperse, but it continues to be the same energy.
The book says that it is false. And the correction is:
The enthalpy change measures the energy of the reaction when it occurs in a closed recipient with rigid walls and at constant pressure.
Could someone (Master Astronuc) clarify me? Thank you.
