The critical point of CCl 4 is 283°C and 45 atm pressure.Liquid CCl 4 has a vapor pressure of 10.0 atm at 178°C.Which of the following statements must be true?

The triple point must be less than 178°C because at 178°C, the vapor pressure is already 10 atm, indicating that the substance is in the liquid phase at this temperature and pressure.
