If enthalpy of fusion and enthalpy of vaporization of sodium metal are

1.	If enthalpy of fusion and enthalpy of vaporization of sodium metal are 2.6 kJ mol-1 and 98.2 kJ mol-1 respectively, calculate the enthalpy of sublimation of sodium.
Answer» ∆_fusH^Θ = 2.6 kJ mol⁻¹ ∆_vapH^Θ = 98.2 kJ mol⁻¹ ^{\(\therefore\)}Δ_subH^Θ = Δ_fusH^Θ + Δ_vapH^Θ = 2.6 + 98.2 = 100.8 kJ mol⁻¹

If enthalpy of fusion and enthalpy of vaporization of sodium metal are 2.6 kJ mol-1 and 98.2 kJ mol-1 respectively, calculate the enthalpy of sublimation of sodium.

Answer»

∆_fusH^Θ = 2.6 kJ mol⁻¹

∆_vapH^Θ = 98.2 kJ mol⁻¹

^{\(\therefore\)}Δ_subH^Θ = Δ_fusH^Θ + Δ_vapH^Θ

= 2.6 + 98.2

= 100.8 kJ mol⁻¹
