Standard Form of molecule

Postby kennedyp » Thu Jan 30, 2020 4:50 pm

How do we know that a molecule is in its "standard form"?

A substance is in its standard form when at 25 degrees C and 1atm. There is no way to memorize what phase each substance would be in at these conditions.

The standard form of a molecule has given values associated with it. The standard form is observed at 25 degrees Celsius, 1 atm.

As long as the pressure is 1 atm and the temperature is 25C, the substance is in its standard form.

By standard form, is this referring to the STP vs. NTP thing?

Standard form of the substance is the form that a substance naturally occurs as in 25 degrees Celsius and 1 atm conditions. The most important thing to remember about standard form is that some molecules exist in their diatomic form at these conditions.
