question 4

Multiple Choice

Consider the reaction N₂ + O₂ ⇌ 2NO. At 1800 C, this reaction has an equilibrium constant of 1.2  10^-4. During the course of the reaction, a sample of the reaction mixture is taken, and the concentrations of each component are found to be as follows: [N₂] = 0.055 mol L^-1, [O₂] = 0.081 mol L^-1, and [NO] = 0.003 mol L^-1. In which direction must the reaction proceed for it to reach equilibrium?

• A) The reaction must proceed from right to left.
• B) The reaction must proceed from left to right.
• C) The reaction is already at equilibrium.
