Answer to Question #119150 in General Chemistry for Abigail Rouse

Question

N₂ (g) + O₂ (g)<--> 2 NO (g)for which the K at 2273 K is 1.2 X 10⁻⁴. What is the concentration of NO if N₂=.166 M and O₂ =.145 M

Answer 1

K = [NO]²/([N₂]x[O₂]) $\implies$ [NO] = (Kx[N₂]x[O₂])^1/2 = (1.2x10^-4x0.166x0.145)^1/2 = 0.0017 M
