At equilibrium, the equilibrium constant for the following hypothetical reaction is two (K_eq = 2) , [A] = 4, [B] = 8, and [AB] = 16 at 25 °C. AB + Heat $\rightarrow$ A (g) + B (g)
After a stress has been absorbed by the reaction, the new equilibrium concentrations are: [A] = 2, [B] = 1, and [AB] = 64. The stress absorbed by the equilibrium system ________.

Question

At equilibrium, the equilibrium constant for the following hypothetical reaction is two (K_eq = 2) , [A] = 4, [B] = 8, and [AB] = 16 at 25 °C. AB + Heat

\rightarrow

A (g) + B (g)
After a stress has been absorbed by the reaction, the new equilibrium concentrations are: [A] = 2, [B] = 1, and [AB] = 64. The stress absorbed by the equilibrium system ________.

Quizplus · Accepted Answer

The stress absorbed by the equilibrium system was an increase in the concentration of [AB]. This is because the equilibrium constant (K_eq) is a constant at a given temperature, and the reaction will shift to the side that consumes the added reactant or produces the added product in order to re-establish equilibrium. In this case, the increase in [AB] will cause the reaction to shift to the left, consuming [AB] and producing [A] and [B].
