Answer to Question #188593 in General Chemistry for mike

Question

.The equilibrium constant Kc for the dissociation of dinitrogen tetroxide

is 4.65  X  10-3 at 25oC.

N2O4(g)            2NO2(g)

[0.00020]=[NO2]

[0.098]= [N2O4]

Starting with 0.100mol of N2O4(g) in a 4.00L reaction vessel, calculate the concentrations of N2O4(g) and NO2(g) at equilibrium.

Answer 1

Concentration of N2O4 =2.78M

Concentration of NO2=1.53M
