At 2010K, the equilibrium constant Kc is 4*10^-4 for the following:
N2+O2-->2NO
If the equilibrium concentration of N2 is .28M and O2 is .38M, what is the equilibrium concentration of NO?
a)1.8*10^-9
b)2.1*10^-5
c)4.3*10^-5
d)6.5*10^-3

    I have removed your other 6 posts. You are welcome to post again, but be sure you include what you know about each question so far and what your SPECIFIC QUESTION is.

    Kc = (NO)^2/(N2)(O2)
    You have only one unknown. Solve for that.
