Standard Enthalpy of formation of an element

Postby Jacob Afable 3J » Sat Jan 09, 2016 11:48 am

By definition, the standard enthalpy of formation of an element in its most stable form is zero. In lecture, I found a memory tool quite helpful that Professor Lavelle addressed in class. "If you're at sea level, what is your altitude? The altitude difference is zero." It makes sense because no reaction is taking place when an element is in its most stable form; therefore the change in enthalpy will be zero.

Yes, this is a sensible analogy!
