Choose the incorrect statement from the following

• A

  At Boyle temperature a real gas obeys ideal gas law over an appreciable range of pressure
• Correct answer
  B

  Critical temperature of $\mathrm{CO}_2$ is $27.5^{\circ} \mathrm{C}$
• C

  Above critical temperature, a real gas behaves like an ideal gas
• D

  At room temperature and 1 atm pressure the compressibility factor $(Z)$ for $\mathrm{H}_2$ gas is greater than 1

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