Question 37

Multiple Choice

Consider this reaction at equilibrium: 2H2O2(g) Consider this reaction at equilibrium: 2H<sub>2</sub>O<sub>2</sub>(g) 2H<sub>2</sub>O(g) + O<sub>2</sub>(g) ,ΔHº<sub>rxn</sub> = -210 kJ/mol If the volume of the system is expanded at constant temperature,what change will occur in the position of the equilibrium? A) A shift to produce more H<sub>2</sub>O<sub>2</sub> B) A shift to produce more O<sub>2</sub> C) No change will occur. D) A shift to produce less H<sub>2</sub>O E) The pressure decreases. 2H2O(g) + O2(g) ,ΔHºrxn = -210 kJ/mol
