An ideal gas obeying kinetic gas equation can be liquefied if
Correct answer: C. Its pressure is more than critical pressure but temperature is less than critical temperature
- A. Its temperature is more than critical temperature
- B. Its pressure is more than critical pressure
- C. Its pressure is more than critical pressure but temperature is less than critical temperature
- D. It cannot be liquefied at any value of P and T.
Explanation
An ideal gas can be liquefied if its conditions (pressure and temperature) are above the critical point. The critical point is characterized by a critical temperature (Tc ) and critical pressure (Pc ).At the critical point, the distinction between the liquid and gas phases disappears. To liquefy an ideal gas, you need to operate at conditions beyond the critical temperature but below the critical pressure

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
