i have difficulties in this question.any help would be appreciated.

1) 2No(g)-> N2(g)+O2(g)

at 1800K,K is 8.36*10^3.what concentration of NO(g) is in equilibrium with N2(g) at a concentration of 0.0500mol/liter and O2(g) at a concentration of 0.500 mol/liter?

  1. The equilibrium constant expression is:
    K(eq)=[N2][O2] / [NO]^2 = 8.36*10^3
    Substitute the concentrations given and solve for [NO]
