The air pollutant NO is produced in automobile engines because of the high-temperature reaction below. If the initial concentrations of N2 and O2 at 1000 K are both 1 M, what are the concentrations of NO, N2, and O2 when the reaction mixture reaches equilibrium? Assume the product concentration is initially zero. N2(g) + O2(g) 2 NO(g) Kc = 1.6 10-1 at 1000 K. [NO]= [N2]= [O2]=
