At a certain temperature, Keq for the following reaction between sulfur dioxide and nitrogen dioxide is 4.8.   SO2(g)   +   NO2(g)   ↔   NO(g)   +   SO3(g)   SO2(g) and NO2(g) have the same initial concentration:   0.36 mol/L.  What amount of SO3(g) is present in a 5.0 L container at equilibrium?

Dinitrogen tetroxide was used as part of the fuel for the lunar lander in the Apollo missions.  It establishes the equilibrium below. N2O4 (g)   <-->   2 NO2 (g)     Kp = 0.133 If an unknown pressure of N2O4 was added to a reaction flask, and 90.0% of the N2O4 still remains once equilibrium has been established, what was the initial pressure that was added to the reaction flask?
