Chlorofluorocarbons (CFCs) are inert substances that were long used as refrigerants. Because CFCs are inert, when they are released into the atmosphere they are not rapidly destroyed in the lower atmosphere. Instead, they are carried into the stratosphere, where they cause ozone depletion. A method for destroying CFCs stockpiles passes the CFCs through packed sodium oxalate,Na₂C₂O₄ , powder at 270. The reaction for Freon-12,CF₂CL₂ , is
CF₂Cl₂(g) + 2Na₂C₂O₄ (s) = 2NaF(s) + 2NaCl + C(s) +4CO₂ (g)

QUESTION) If you had to design a reactor to carry out the reaction at a maximum safe pressure of 10.0 while destroying 1.05 of Freon-12, what volume reactor would you need?
plz help, urgently need help, ill be really thankful.
