Question

Nitrogen and oxygen gases may react to form nitrogen monoxide. At 1500 C, Kc equals 1.0 10-5.
N2(g) + O2(g) 2 NO(g)
If 0.030 mol N2 and 0.030 mol O2 are sealed in a 1.0 L flask at 1500 C, what is the concentration of NO(g) when equilibrium is established?
A.3.0 10-7 M
B.4.7 10-5 M
C.9.5 10-5 M
D.3.0 10-2 M
E.9.1 101 M
