Equilibrium and Inert Gas Addition
A researcher asserts that adding a noble gas to a reaction at equilibrium while maintaining constant pressure will cause the equilibrium position to shift. Which of the following statements identifies a conceptual flaw in this assertion?
A
Noble gases react with the reactants, changing the equilibrium constant.
B
Adding a noble gas at constant pressure does not change the partial pressures of the reactants or products, thus not affecting the equilibrium position.
C
Adding a noble gas should increase the volume, causing a shift in equilibrium.
D
A noble gas decreases the total pressure, which directly shifts the equilibrium.
