When N2O4 is allowed to dissociate into NO2 at 25 degrees Celsius at a total pressure of 1 bar, it is 18.5% dissociated at equilibrium, so K=0.141. If the system is allowed to expand as N2 is added at a cosntant total pressure of 1 bar, what will be the equilibrium degree of dissociation when the N2 partial pressure is 0.6 bar?
