Some SO2 and O2 are mixed together in a flask at 1100 K in such a way ,that at the instant of mixing, their partial pressures are, respectively, 1.00 atm and 0.500 atm. When the system comes to equilibrium at 1100 K, the total pressure in the flask is found to be 1.35 atm. Given: 2SO2(g) + O2(g) ⇌ 2SO3(g); ΔrH = − 198.2 kJ. mol-1 1.1 Calculate Kp at 1100 K
