What is the keq value for the following reaction at equilibrium at a temperature of 298K if the concentrations (in mol/L) of the reactants and products are [N2O4] = 0.0450 and [NO2] = 0.0161?
N2O4(g) <--> 2NO2(g)

when Keq is a constant which characteristic for every reaction, relates the

concentration of reactants and products at equilibrium at given temperature and

pressure.

and when the Keq expression = concentration of products/concentration of reactants.

Keq = [NO2]^2 / [N2O4]

when [NO2] = 0.0161 M

and [N2O4] = 0.045 M

so by substitution:

Keq=  0.0161^2 / 0.045

      = 5.8 x 10^-3
