Explanation:
Equilibrium in the reaction:
- When H2 and I2 are mixed, they react to form HI according to the equation: H2 + I2 ⇌ 2HI.
- At equilibrium, the concentrations of reactants and products remain constant.
Amount of HI formed:
- The amount of HI formed at equilibrium depends on the initial concentrations of H2 and I2, as well as the equilibrium constant for the reaction.
- It is not necessarily equal to the amount of H2 dissociated, as the equilibrium position is determined by the relative concentrations of the reactants and products.
HI dissociated stops:
- Once equilibrium is reached, the forward and reverse reactions occur at equal rates, resulting in the concentrations of H2, I2, and HI remaining constant.
- However, some HI may still dissociate and reform due to the dynamic nature of equilibrium.
Reaction stops completely:
- The reaction does not stop completely at equilibrium; instead, it continues at a constant rate in both the forward and reverse directions.
- The concentrations of all species in the reaction remain constant, indicating a dynamic equilibrium state.
Therefore, the correct answer is option 'D' - None of these. At equilibrium, the reaction does not stop completely, and the amount of HI formed is not necessarily equal to the amount of H2 dissociated.
