The equilibrium 2NO2(g)⇌N2O4(g) (Kp=0.16 at 350\,K) is established in a rigid 2.0-L container at 350\,K. Which of the following single changes will cause the greatest shift toward formation of N2O4?
a) Doubling the temperature at constant volume
b) Compressing the system to 1.0L at constant temperature
c) Injecting Ne gas until the total pressure doubles (volume constant)
d) Removing one-half of the NO2 while keeping volume and temperature constant
