Reversible Reactions - Experiment

The video tutorial explains the evaporation of water in a closed container, using a manometer to measure pressure changes. Initially, the pressure increases as water evaporates, but eventually stabilizes, indicating equilibrium. At this dynamic equilibrium, evaporation and condensation occur simultaneously, with no net change in water levels. The concept of reversible reactions is introduced, where the rate of evaporation equals the rate of condensation, maintaining constant concentrations of reactants and products.
