An engineer examining the oxidation of SO2 in the production of sulfuric acid determines that Kc = 1.7 × 108 at 600 K: 2 SO2(g) + O2(g) ⇌ 2 SO3(g) At equilibrium, the partial pressure of SO3 = 130 atm and the partial pressure of O2 = 120 atm. Calculate the partial pressure of SO2.

Equal numbers of moles of he(g), ar(g), and ne(g) are placed in a glass vessel at room temperature. if the vessel has a pinhole-sized leak, which of the following will be true regarding the relative values of the partial pressures of the gases remaining in the vessel after some of the gas mixture has effused?

How much would the freezing point of water decrease if 4 mol of nacl were added to 1 kg of water (kf=1.86 degrees c/(mol/kg) for water and i=2 for nacl a- 7.44 degrees c b- 14.88 c 3.72 d 1.86
