Short Answer TypeWhat are the limitations of Vander Waal's equation of state?
The values of 'a' and 'b' are not constant over the entire ranges of temperatures and pressures, so van der Waal’s equation is also valid for specific ranges of temperatures and pressures. Real gases deviate from van der Waal’s equation especially at too low temperatures or too high pressures.
