A sample of nitrogen dioxide is placed in a container at 250°C and 1 atm, where it decomposes according to the following equation: 2NO2(g) ↔ 2NO(g) + O2(g)The initial concentration of NO2 is 0.10 M, and the equilibrium constant (Kc) at this temperature is 4.0 x 10^-3. If the volume of the container is suddenly decreased to one-half of its original volume, causing the pressure to double, what will happen to the amount of NO and O2 present at equilibrium? Calculate the new equilibrium concentrations of NO and O2.
