Gather data: experiment with a variety of initial concentrations of no2 and n2o4. for each set of initial concentrations, use the gizmo to determine the equilibrium concentrations of each substance. in the last column, find kc for that trial. run three trials for each set of initial conditions.

Solution :

Initial concentration               Equilibrium concentration          

  (mol/L)                                           (mol/L)

     0                  46.42

     0                  47.61

     0                  46.73

     0                  46.86

                                    46.39

                                        46.42
