Standard State

Postby AGaeta_2C » Sun Jan 26, 2020 9:40 pm

How do you know the standard state of a molecule? Its easy for molecules like nitrogen and oxygen, but how would we know for other molecules?

The standard state of a molecule is given by its phase at 25 degrees Celsius, and 1 atm. Mercury and Bromine are liquid, while the noble gases and H, O, and N are gases. The rest of the elements are solid.

The term standard state refers to the state of an element at 25 degrees celsius and 1 atm. The majority are solids with few exceptions. I wouldn't say that this is something we calculate, rather memorize those which are gasses and liquids since there are only 13.
