Answer to Question #120965 in Physical Chemistry for Samson

Question

Under what conditions does the behaviour of real gases deviate from that predicted by the ideal gas law?

Answer 1

The behavior of real gases usually agrees with the predictions of the ideal gas equation to within 5% at normal temperatures and pressures (Normal temperature -  20^oC (293.15 K, 68^oF), pressure -1 atm (101.325 kN/m², 101.325 kPa, 760 torr). At low temperatures or high pressures, real gases deviate significantly from ideal gas behavior
