Therefore for the above reaction, saying that $\Delta_\mathrm{r}H^\circ = -572~\mathrm{kJ~mol^{-1}}$ means that.

Back to top Standard heat of formation of NaBr is -360 kJ mol-1. Energy needed to vaporize one mole of Br 2 (l ) to give Br 2 ( g) is 31 kJ mol-1. The energy needed to change 1 mol Na(s) to 1 mol Na( g) is 107.8 kJ. The first ionization energy of Na is 495.4 kJ mol-1. The bond energy of Br 2 is 192 kJ per mole of Br Br bonds. The lattice energy of NaBr is = 801 kJ/mol IE 2 = 2427 kJ/mol IE 3 = 3660 kJ/mol IE 4 = 25025 kJ/mol Since there is a very large increase in IE 4 compared to IE 3, this element would be expected to have 3 valence electrons.

so to convert from J to KJ we add in this factor. 1 J x (1KJ/1000J) as you can see here the Joules cancel out and you are left with KJ. to determine kJ/mol you divide the kJ by the number of moles used up . so if say 7 moles were used and you know 7 kJ were used you would have 7 kJ/7 mol = 1kJ/mol some people suggests that i cannot be done but i think its possible because mole is a set number, Avogadro's constant.

### Kilojoules per mole (kJ/mol, kJ · mol-1) A Joule, J, is the SI unit of energy and is defined as one kg·m 2 /s 2. The prefix "kilo" means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence "per mole".

1 J x (1KJ/1000J) as you can see here the Joules cancel out and you are left with KJ. to determine kJ/mol you divide the kJ by the number of moles used up . so if say 7 moles were used and you know 7 kJ were used you would have 7 kJ/7 mol = 1kJ/mol some people suggests that i cannot be done but i think its possible because mole is a set number, Avogadro's constant.
