Vedclass · Answer

(D) Sublimation is the process of direct conversion of a solid into a gas. According to Hess's Law,the enthalpy change for a process is the same whether it occurs in one step or multiple steps. Solid to gas can be represented as: $1. 	ext{Solid} ightarrow 	ext{Liquid} \quad (\Delta_{fus} H)$ $2. 	ext{Liquid} ightarrow 	ext{Gas} \quad (\Delta_{vap} H)$ Therefore,the total enthalpy change for sublimation is the sum of the enthalpy of fusion and the enthalpy of vaporization: $\Delta_{sub} H = \Delta_{fus} H + \Delta_{vap} H$.
