NO2 has a higher boiling point than CO2 because the nitrogen radii is larger than carbon. The bigger the atom the more intermolecular force that is created...this requires more energy to break causing a higher boiling point.

Sulfur is larger and therefore has a larger intermolecular force than oxygen. Intermolecular force increases the amount of energy needed to break the bonds, and increases the boiling point.

the fact is that they actually have similar intermolecular forces. the key difference is in molar masses.

Boiling points:

CO: −191.50 °C

O2: −182.95 °C so this is higher!

CO is a polar (charge asymetric) molecule, N2 is symetrical and therefore non-polar

NO will have a slight dipole and N2 does not. Thus, the intermolecular forces between NO molecules is stronger than those between N2 molecules.

CO has greater intermolecular forces holding the CO molecules together than does N2, so it has a higher boiling point.

How do modern ammonia production facilities obtain pure hydrogen and pure nitrogen for the Haber process?

Hydrogen is produced by reacting methane (CH4(g),(natural gas)) with steam (H2O(g)), producing carbon dioxide (CO2(g)) and hydrogen (H2(g)). Nitrogen (N2(g)) is obtained by the fractional distillation of air (~78% N2(g)). Fractional distillation is a process by which the components in a chemical mixture are separated according to their different boiling points. Vapours from a boiling solution are passed along a cooled column. The temperature of the column gradually decreases along its length. Components with a higher boiling point condense on the column and return to the solution; components with a lower boiling point pass through the column, are condensed, and are collected in a suitable collecting vessel.


How do you find the boiling point of N2?

It will depend on atmospheric pressure. You can use the Clausius-Clapeyron equation In this form ln (P2/P1) =( or approximately equals )= -ΔHm ( 1/T2 - 1/T1 )/R The normal bp of N2 is 77.4 K at 760 Torr, ΔHm for N2 is 5.58 kJ/mol, R is 8.314 J/mol.K. Plug in above constants, and you can supply your own temp or pressure into T1 or P1 and solve for the other. Make sure you get your units right! I leave it up to you to work them out. This only works for ideal gases close to the normal boiling point.


Which has more molecules 16g of CO or 20g of N2?

There are 6.023x10^23 molecules in one mole of a compound. So now, you have to find how many moles of each compound you have. CO's molecular weight is (12+16) = 28 g/mol N2's molecular weight is (14+14) = 28 g/mol So you find the moles of each. moles of N2 = 20g/ 28g/mol = .714 moles moles of CO = 16g / 28 g/mol = .571 moles So, N2 has (.714 *6.023x10^23) has 4.3 x10^23 molecules and CO (.571 *6.023x10^23) has 3.4x10^23 molecules. So, 20g of N2 has more molecules than 16g of CO
