Explain the following with relevant examples. Liquid-vapour equilibrium |
|
Answer» Solution :Liquid-VAPOUR equilibrium `SQUARE` There exists an equilibrium between the liquid PHASE and the vapour phase of a substance. For example, liquid water is in equilibrium with its vapour at 273 K and 1 atm pressure in a closed vessel. `H_(2)O(l)hArrH_(2)O(g)` `square` Here Rate of evaporation = Rate of condensation `square` The temperature at which the liquid and vapour phase are at equilibrium is CALLED the boiling point and consensation point of the liquid. |
