I’m doing an assignment for my thermodynamics class regarding the condensation of ammonia. I’ve been doing some research regarding why it’s a gas at STP and I’m having some difficulty understanding. As I understand, the intermolecular forces are usually sufficient in explaining the phase of a compound at STP. But NH3 displays hydrogen bonding, the strongest IMF. I read in a journal that the low density of this compound explains it being a gas, but I’m wondering if I’m missing something. This seems trivial, but I don’t understand why the strong hydrogen bonding doesn’t seem to play a role in its standard state. Any help is appreciated!
