The system remains unchanged

Nitric oxide an important pollutant in air is formed from the elements nitrogen and oxygen at high temperatures such as those obtained when gasoline burns in an automobile engine. At 2000°C K for the reaction N2(g) O2(g) 2NO(g) is 0.01. Predict the direction in which the system will move to reach equilibrium at 2000°C if 0.4 atm N2 0.1 atm O2 and 0.08 atm NO are placed in a container.A) The system remains unchanged.B) The concentration of NO will decrease; the concentrations of N2 and O2 will increase.C) The concentration of NO will increase; the concentrations of N2 and O2 will decrease.D) The concentration of NO will decrease; the concentrations of N2 and O2 will remain unchanged.E) More information is necessary.please explain
