(a)

Interpretation:
Calculate the free energy values
Concept Introduction:
Chemical equilibrium: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved; the concentrations of reactant and products become constant.
Homogeneous equilibrium: A homogeneous equilibrium involved has a everything present in the same phase and same conditions, for example reactions where everything is a gas, or everything is present in the same solution.

Answer to Problem 15.104QP
The system equilibrium reaction on given respective images (a-c) are shown below.
The given equilibrium reaction (Image (A) as positive and Images (ii and iii) has negative
Explanation of Solution
Calculate and analyze the (Qr) values for equilibrium reactions.
Analysis for image (1): The equilibrium process (a) also smallest equilibrium constant, here three products are present in the diagrams.
Analyzing image (2): Further we consider the equilibrium images (2), this process has the smallest equilibrium constant (Kc), because low amount of reactant present in this equilibrium.
Analyzing image (3): Given the equilibrium reaction (3) has largest equilibrium constant, because the three diagrams, there is the most products present at equilibrium process, and this products indicated the respective image.
