The equilibrium constant (KP) is 0.13 at a particular temperature for the reaction: N2O4(g) ? 2NO2(g) Given the following sets of initial conditions, what is the net change that must occur for the reaction to reach equilibrium? Does the reaction shift left to reach equilibrium, does the reaction shift right to reach equilibrium or is the reaction at equilibrium at these initial concentrations so no net change will occur? 1.PNO2 = 0.137 atm, PN2O4 = 0.144 atm 2.PNO2 = 0.081 atm, PN2O4 = 0.05 atm 3.PNO2 = 0.132 atm, PN2O4 = 0.054 atm 4.PNO2 = 0.082 atm, PN2O4 = 0.13 atm 5.PNO2 = 0.064 atm, PN2O4 = 0.07 atm
