the equilibrium constant for the reaction

N2O4(g) <=======> 2NO2(g)

is Kc = 4.66 x 10 -3 at 298K. Calculate the following when 0.800mol of N2O4(g) is injected into a closed 1.00L container.

a). The concentration of each gas once equilibrium is reached.
b). The new equilibrium concentrations if the volume is suddenly halved (still at 298K)
