प्रश्न
What is enthalpy change and volume change of mixing of two components forming an ideal solution?
Advertisements
उत्तर
- No heat is evolved or absorbed when two components forming an ideal solution are mixed. Thus, ∆mixH = 0.
- There is no volume change when two components forming an ideal solution are mixed. Thus, ∆mixV = 0.
