Interpretation:The equilibrium expression of
Concept introduction: Heterogeneous equilibrium can be defined as equilibrium where the components (reactants and products) are present in different phases.
(a)
Answer to Problem 27A
The equilibrium expression is
Explanation of Solution
Equilibrium expressions used to determine the changes in concentration that happens as the reaction approaches equilibrium. Aqueous solutions and gases change their concentrations considerably during the course of reaction. On the other hand, pure liquids and solids do not change their concentration much as reaction moves towards equilibrium since they are present in large excess.
Hence pure liquids and solids are not included in equilibrium expression equation.
The reaction is:
The equilibrium expression is
