Answer to Question #147663 in General Chemistry for claudia

Question

At a certain temperature K for the reaction 2NO2 ⇆ N2O4 if the equilibrium concentrations of N2O4 is 30.0 mol/L and NO2 is 2.0 mol/L, what is the equilibrium constant?

Answer 1

K = [N2O4]/[NO2]^2 = (30 mol/L)/(2 mol/L)^2 = 7.5 L/mol
