1.Plot the equilibrium graph (# moles verses time) for the following reaction (in a 1.0 L container):

N2 (g) + 2 O2 (g) < ------->2NO2 (g) H $ + 66.4 kJ mol-1

Initially there is 4.5 moles of N2, and 7.5 moles of O2 and 0(zero) moles of NO2.

(a) After 2 minutes equilibrium is attained with the following equilibrium concentrations:

[N2] $ 2.5 mol/ L , [O2] $ 3.5 mol/L, [NO2] $ 4.0 mol/L

(b) Show the influence after 3 min of adding N2, to the equilibrium, equilibrium is attained at 5 minutes.

(c) show the influence at 5 min of increasing the volume of the system.

(d) show the affect at 7 min of decreasing the temperature of the system.

(e) show the affect at 9 min of increasing the pressure of the system.

(f) show the affect 11 min of removing NO2 .

NE: Assume equilibrium is reached 2 min after each change
