Gas constant (R) = 8.31 J K–1 mol–1

Molar volume of an ideal gas at 273 K and 1.01 × 105 Pa = 2.24 × 10–2 m3 mol–1 (= 22.4 dm3 mol–1)

Planck’s constant (h) = 6.63 × 10–34 J s

Specific heat capacity of water = 4.18 kJ kg–1 K–1 (= 4.18 J g–1 K–1)

Ionic product constant for water (Kw) = 1.00 × 10–14 at 298 K

1 atm = 1.01 × 105 Pa

13. Lattice enthalpies at 298 K (experimental and theoretical values)

The lattice enthalpy values lattice( )∆HÖ given relate to the endothermic process for a solid crystal

breaking into gaseous ions.

For example, for an alkali metal halide:

MX(s) → M+(g) + X–(g)

Experimental valuesThe data in these two tables are experimental values obtained by means of a suitable Born–Haber cycle.
