Question

Quizplus · Accepted Answer

The correct equation for the molar heat of sublimation (ΔH_sub) is the sum of the molar heat of fusion (ΔH_fus) and the molar heat of vaporization (ΔH_vap). This is because sublimation involves a solid turning directly into a gas, effectively undergoing both fusion (solid to liquid) and vaporization (liquid to gas) in one step.
