Q. Consider the following phase diagram of CO2 (not to scale). At equilibrium, the INCORRECT statement is:

A. At 200 K, on increasing the pressure from 1 to 50 atm, CO2 gas condenses to liquid.

B. It is not possible to obtain liquid CO2 from gaseous CO2 below 5.11 atm.

C. Both liquid and gas phase of CO2 coexist at 298.15 K and 67 atm.

D. With increasing pressure, the melting point of solid CO2 increases.

Ans: At 200 K, on increasing the pressure from 1 to 50 atm, CO2 gas condenses to liquid.
