Options

A. In the van der Waal's equation of state `(P+(a)/(V_(m)^(2)))(V_(m)-b)=RT` for `NH_(3)` and `N_(2)`. The value of 'a' for `NH_(3)` is larger than that of `N_(2)`
B. Pressure exerted by real gs is lesser than that exerted by ideal gas under all conditions.
C. At high pressure, pepulsive forces diminates in real gases.
D. If a real gas follows the equation ,`P(V_(m)-b)=Rt`, it can easily be liquefied.
