Equilibrium of Iodine Vapour in a Closed Vessel
Introduction:
When solid iodine is placed in a closed vessel, it sublimes to form violet vapour. After some time, equilibrium is attained between the solid iodine and its vapour phase. At this point, the intensity of colour of the violet vapour is a matter of interest.
Equilibrium:
Equilibrium is a state of balance in a chemical reaction where the rate of the forward reaction is equal to the rate of the backward reaction. In the case of iodine vapour in a closed vessel, the forward reaction is the sublimation of solid iodine to form vapour, while the backward reaction is the condensation of the vapour to form solid iodine.
Intensity of Colour:
The intensity of colour of the violet vapour at equilibrium is constant. This is because the rate of the forward reaction is equal to the rate of the backward reaction. As a result, the concentration of iodine vapour in the closed vessel remains constant, and so does the intensity of its colour.
Explanation:
When solid iodine is placed in a closed vessel, it starts to sublime to form violet vapour. The rate of sublimation is initially high, and so the concentration of iodine vapour in the vessel increases rapidly. As a result, the intensity of colour of the violet vapour also increases. However, as the concentration of iodine vapour increases, the rate of the backward reaction (condensation) also increases. Eventually, a point is reached where the rate of the forward reaction (sublimation) is equal to the rate of the backward reaction (condensation). At this point, equilibrium is attained, and the concentration of iodine vapour remains constant. As a result, the intensity of colour of the violet vapour also remains constant.
Conclusion:
In conclusion, when solid iodine is placed in a closed vessel, the intensity of colour of the violet vapour at equilibrium is constant. This is because the rate of the forward reaction (sublimation) is equal to the rate of the backward reaction (condensation), resulting in a constant concentration of iodine vapour in the vessel.
