Question

Question: There is only one value of the equilibrium constant for a particular system at a particular temperature, but there are an infinite number of equilibrium positions. Explain.

Short answer

Answer

The infinite number of equilibrium positions is possible for any system at a constant temperature, but all the equilibrium positions have the same equilibrium constant value.

Step-by-step solution

Equilibrium constant

The equilibrium constant for a specific system gives us a definite number at a constant temperature because it is calculated at equilibrium conditions. Therefore, it gives a single number for different initial conditions.

Explanation of why there is only one value of the equilibrium constant for a particular system

A specific set of partial pressures/concentrations for the system/reaction that fulfills the equilibrium constant K equation is called an equilibrium position.

There are infinite equilibrium positions for a particular system at a constant temperature. Different partial pressures/concentrations have different equilibrium positions, but these positions have the same K value.
