Formation of Hydrogen Iodide

The video tutorial explains the reversible reaction of hydrogen iodide formation, where hydrogen and iodine gases react at 730 Kelvin. Initially, no reaction occurs, but after 15 seconds, hydrogen and iodine molecules start forming hydrogen iodide. The forward reaction rate increases as the concentration of reactants decreases. After 30 seconds, the backward reaction begins, leading to dynamic equilibrium where the rates of forward and backward reactions are equal. A graph illustrates the concentration changes of reactants and products over time, highlighting the dynamic equilibrium stage.

What observations indicate that the reaction has reached dynamic equilibrium?

How does the graphical representation of the reaction illustrate the concept of dynamic equilibrium?
