Equilibrium Systems: An Equilibrium System For The Reaction Between Hydrogen And Iodine
An equilibrium system is a system in which the forward and reverse reactions occur at the same rate, so that the concentrations of the reactants and products do not change over time. The equilibrium constant is a number that describes the relative amounts of reactants and products at equilibrium.
Le Chatelier’s principle states that if a change is made to an equilibrium system, the system will shift in a direction that counteracts the change.
The Reaction between Hydrogen and Iodine
The chemical reaction between hydrogen and iodine is a reversible reaction that can be represented by the following equation:
“`H2 + I2 ⇌ 2HI“`
The equilibrium constant for this reaction is:
“`K = [HI]^2/[H2][I2]“`
The equilibrium constant is a function of temperature. The value of K increases with increasing temperature.
Experimental Methods
