Standard States

Postby Maya Gollamudi 1G » Sun Feb 02, 2020 4:26 pm

What does it mean for reactants/products to be in their standard states?

I believe it means the most stable form of that molecule/element. For example, the standard state of oxygen is O2 because this is the most stable way for oxygen to exist and is thus the most common, or "standard" form.

standard states also mean that since the molecule/element is in its most stable form, it will not undergo a change that changes enthalpy. Therefore, enthalpy of standard state molecules/elements are zero.
