Dinitrogen tetroxide and NO2 are in equilibrium at 25 °C under a certain set of reaction conditions. A sample of N2O4(g) is placed in an empty cylinder at 25 °C. After equilibrium is reached the total pressure is 1.5 atm and 16% (by moles) of the original N2O4(g) has dissociated into NO2(g). a) Calculate the value of Kp at 25 °C b) If the volume of the cylinder is increased until the total pressure is 1.0 atm, what will the new equilibrium pressures of N2O4(g) and NO2(g) be, assuming no change in Kp? c) What percentage (by moles) of the original N2O4(g) is dissociated at the new equilibrium position in b?

Question
Dinitrogen tetroxide and NO2 are in equilibrium at 25 °C under a certain set of reaction conditions. A sample of N2O4(g) is placed in an empty cylinder at 25 °C. After equilibrium is reached the total pressure is 1.5 atm and 16% (by moles) of the original N2O4(g) has dissociated into NO2(g).
a) Calculate the value of Kp at 25 °C
b) If the volume of the cylinder is increased until the total pressure is 1.0 atm, what will the new
equilibrium pressures of N2O4(g) and NO2(g) be, assuming no change in Kp?
c) What percentage (by moles) of the original N2O4(g) is dissociated at the new equilibrium position in b?
