8.1.7 Practice: General Equilibrium Xing Chan
1. The formation of water from its elements at 1200 K can be written as a series of coupled reactions: (1
Suppose the system has the following concentrations:
] = 0.0041
] = 0.0062
O] = 2.3
Predict the direction in which the system will shift to reach equilibrium. Justify your answer.
With the given concentrations, the equilibrium direction will shift to the left (reactants)
2. The figure below shows two possible methods for the production of acetyl CoA from acetate as part of
the biosynthesis of fatty acids in the body. The first method is a direct reaction, and the second method
involves coupled reactions.
