Consider the following equilibrium: O 2 (g)+ 2F 2 (g) 2OF 2 (g); K p = 2.3 × 10 -15 Which of the following statements is true?

According to Le Chatelier's principle, the equilibrium will shift towards the side with fewer moles of gas (in this case, only one mole of gas on the left side). Therefore, the reaction mixture will consist of mainly O 2 (g) and F 2 (g) at equilibrium.
