At the normal boiling temperature of iron, TB = 3330 K, the rate of change of the vapor pressure of liquid iron with temperature

Margaret [11]

The molar latent enthalpy of boiling of iron at 3330 K is ΔH = 342 $\times$ 10^3 J.

<u>Explanation:</u>

Molar enthalpy of fusion is the amount of energy needed to change one mole of a substance from the solid phase to the liquid phase at constant temperature and pressure.

d ln p = (ΔH / RT^2) dt

(1/p) dp = (ΔH / RT^2) dt

dp / dt = p (ΔH / RT^2) = 3.72 $\times$ 10^-3

(p) (ΔH) / (8.31) (3330)^2 = 3.72 $\times$ 10^-3

ΔH = 342 $\times$ 10^3 J.
