Standard enthalpy of formation

Postby Ashley Kenney 1E » Fri Jan 25, 2019 7:57 pm

I'm a little confused what standard enthalpy of formation is. Can someone please explain it and its relationship to standard reaction enthalpy?

The standard enthalpy is the standard heat/energy required to form one mole of a substance in its most stable form and that value is zero which makes sense because its already in its most stable form.

Standard enthalpy of formation is basically standard reaction enthalpy for one mole of substance formed from its standard states (most stable form).
