In the Haber Process, the gases N2, H2 and NH3 are passed through the condenser. Its purpose is to condense ammonia into a liquid form. Why does ammonia condense into a liquid form while nitrogen and hydrogen do not?
The boiling points of NH3, N2 and H2 are -33°C, -183°C and -252°C respectively. Note that boiling point is the same as condensation temperature. Their differences in boiling points are due to differences in intermolecular attractions or forces (IMFs). Diatomic nitrogen and diatomic hydrogen are both non-polar molecules because their bonds are non-polar. As such, they don’t experience dipole-dipole interactions. The only forces of attraction...
