CaO can be used as a drying agent. One such application occurs when water is added to dry concrete or cement. The reaction that occurs is
CaO(s) + H2O (l) ⇌ Ca(OH)2 (s)
The product is commonly called slaked lime.
Assuming the commonly used standard-state temperature of 25 °C, calculate ΔSuniv for this reaction using data from the table below.
