Identify whether or not perturbations A through D will affect the equilibrium concentrations of reactants and products in a gas-phase endothermic chemical reaction that involves one or more gases. If all have an effect on the equilibrium concentrations, select response E. Otherwise, identify the one that does not affect the equilibrium concentrations.

Question

Quizplus · Accepted Answer

Increasing the pressure by adding an inert gas to a reaction in the gas phase will not affect the equilibrium concentrations of reactants and products because the inert gas does not participate in the reaction. However, all other perturbations will affect the equilibrium concentrations, which is why option E is incorrect. Adding reactants will shift the equilibrium towards product formation, removing products will shift the equilibrium towards reactant formation, and decreasing the temperature will shift the equilibrium towards reactant formation (as it is an endothermic reaction).
