When SO3(g) is decomposed at the constant pressure P and T= 1000K, the partial pressure of O2 in the equilibrium gas is 0.05 atm. a) What is the pressure P? b) If the pressure of this equilibrated gas is increased to 1.5 atm, to what value must be the temperature to decreased to produce a gas mixture in which pO2= 0.05 atm? Go= - 94600+89.37 T for SO2(g)+1/2O2(g)= SO3(g)
