At equilibrium, the concentrations in this system were found to be [N2] = [O2] = 0.100 M and [NO] = 0.600 M.
N2(g) + O2(g) $\rightleftharpoons$ 2 NO(g)
If more NO is added, bringing its concentration to 0.900 M, what will the final concentration of NO be after equilibrium is re-established?
[NO]final =
M
