A chemist studying the equilibrium N2O4(g)<----->2NO2(g) controls the temperature so that keq ( equilibrium constant)= 0.028. At one equilibrium position, the concentration of N2O4 is 1.5 times greater than the concentration of NO2. Find the concentrations of the two gases in mol/L. (Hint: Let x=[NO2] and 1.5x=[N2O4] in the equilibrium constant expression.)

My answer:
[NO2]= 0.042M

[N2O4]= 0.063M
