Question

The critical point of CCl4 is 283 C and 45 atm pressure. Liquid CCl4 has a vapor pressure of 10.0 atm at 179 C. Which stemaents are flase?

-Vapor and liquid can only be in equalibrium at one temperature, the boiling point

-The normal boiling point of CCl4 must be greater than 178 C

-Liquid CCl4 can exist at temperatures greater than 283 C if the pressure is geeatwer than 45 atm

-Liquid and solid can only be in equalibrium at one termperature , the freezing point

- the triple point must be less than 178 C

Explanation / Answer

By general observation we can say this.. The higher the pressure, the higher the boiling point. So boiling point at 45 atm > bp at 10atm >bp at 1 atm. So the normal boiling point ie boiling point at 1 atm < 178C... Therefore given statement 2 is false
