standard enthalpy

Postby Salma Sudarmadji 2I » Fri Jan 13, 2017 4:54 pm

In the course reader it says that when finding standard enthalpy, we have to make sure everything is in standard state. What does it mean by "standard state"? Can you give an example?
Thanks

Standard state is basically the state of a substance or elements at room temperature. State being solid, Iiquid, or gas. For example, oxygen is a gas in its standard state which is O2 at room temperature where it's stable.
