Determine the pressure based Keq for the reaction: 2SO2(g) + O2(g) = 2SO3(g). given that 1.00x10-2 moles of SO2 and 2.00x10-2 O2 initially placed in a 2.00L reaction chamber. The chamber contained 7.5x10-3 moles of SO3 when equilibrium was established at 727 degrees Celsius. Since you need pressure based constant use ideal gas equation (PV=nRT) to convert moles of gas into pressure with units of atmospheres. R=0.0821 L atm/mol K
