Question

all of these factors can affect (stress) an equilibrium reaction except: (1 point)

○ concentration

○ solubility

○ temperature

○ pressure

Explanation:

To determine the factor that does not stress an equilibrium reaction, we recall Le Chatelier's principle. Concentration changes shift equilibrium (e.g., adding a reactant). Temperature changes affect equilibrium (as reactions have enthalpy changes). Pressure changes (for gaseous reactions) shift equilibrium. Solubility is a property of a substance dissolving, not a stress factor for equilibrium reactions (equilibrium stressors are changes in conditions like conc., temp., pressure).

Answer:

B. solubility
