A technician places 0.50 mol of nitrogen monoxide gas and 0.20 mol of chlorine gas in a 1.00 L sealed container at 100oC. The following equilibrium is established at 4.5 min. 2 NO(g) + Cl2(g) ⇌ 2 NOCl(g) The technician determines that at equilibrium there are 0.30 mol of NOCl, 0.20 mol of nitrogen monoxide and 0.050 mol of chlorine gas. The technician continues recording data for another 3.5 min, noting no change in the concentrations of any of the entities. Construct a graph that represents the changes in concentrations over time for the three entities involved in the reaction shown in the previous information box.
