If a reaction vessel initially contains an N2O4N2O4 concentration of 0.0550 MM at 500 KK , what are the equilibrium concentrations of N2O4N2O4 and NO2NO2 at 500 KK

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
