Question 90

Multiple Choice

Consider the following equilibrium:
O2(g) + 2F2(g) Consider the following equilibrium: O<sub>2</sub>(g) + 2F<sub>2</sub>(g)    2OF<sub>2</sub>(g) ; K<sub>p</sub> = 2.3 × 10<sup>-15</sup> Which of the following statements is true? A) If the reaction mixture initially contains only OF<sub>2</sub>(g) ,then at equilibrium,the reaction mixture will consist of essentially only O<sub>2</sub>(g) and F<sub>2</sub>(g) . B) For this equilibrium,K<sub>c</sub> = K<sub>p</sub>. C) If the reaction mixture initially contains only OF<sub>2</sub>(g) ,then the total pressure at equilibrium will be less than the total initial pressure. D) If the reaction mixture initially contains only O<sub>2</sub>(g) and F<sub>2</sub>(g) ,then at equilibrium,the reaction mixture will consist of essentially only OF<sub>2</sub>(g) . E) If the reaction mixture initially contains only O<sub>2</sub>(g) and F<sub>2</sub>(g) ,then the total pressure at equilibrium will be greater than the total initial pressure.
2OF2(g) ; Kp = 2.3 × 10-15
