For the reaction H₂ (g) + I₂ (g) 2 HI (g) with D H 0, which of the following stresses when applied to an equilibrium mixture will not increase the amount of HI when equilibrium is reestablished?

Quizplus · Accepted Answer

Increasing the volume of the mixture will shift the equilibrium towards the side with more moles of gas, which in this case is the products side. However, adding more reactant (option D) or decreasing temperature (option B) will shift the equilibrium towards the reactants side, decreasing the amount of HI. Option A will increase the amount of HI as more reactant is added, while maintaining the same volume, therefore increasing the pressure, and hence shifting the equilibrium towards the products side to decrease the pressure.
