Q57 / 180 · NEET 2015 (Phase 2) · Chemistry

A gas such as carbon monoxide would be most likely to obey the ideal gas law at:

  • Correct answer
    A
    High temperatures and low pressures
  • B
    Low temperatures and high pressures
  • C
    High temperatures and high pressures
  • D
    Low temperatures and low pressures

Solution

Real gases show ideal gas behaviour at high temperatures and low pressures. This is because at high temperatures and due to low pressure, the molecules will move with a very high speed and the distance between them will be very large and thus the force of attraction between them will be negligible.

Hence, the correct answer is option: 'A'.
