Consider the following phase diagram of $\mathrm{CO_2}$ (not to scale). At equilibrium, the INCORRECT statement is:
(a)At 200 K, on increasing the pressure from 1 to 50 atm, $\mathrm{CO_2}$ gas condenses to liquid
(b)It is not possible to obtain liquid $\mathrm{CO_2}$ from gaseous $\mathrm{CO_2}$ below 5.11 atm
(c)Both liquid and gas phase of $\mathrm{CO_2}$ coexist at 298.15 K and 67 atm.
(d)With increasing pressure, the melting point of solid $\mathrm{CO_2}$ increases.
