Q6. A researcher is working on the degradation of gaseous sulfur trioxide into sulfur dioxide and oxygen gases at 600 K. Once an unknown amount of sulfur trioxide was pumped into an evacuated and sealed flask total pressure of the system found to be at 3.0 atm when equilibrium is established. By using an oxygen detector mole fraction of the oxygen was found to be 0.12. Calculate Kc of this reaction
