Assertion : Compressibility factor (Z) is the ratio of actual molar volume of a gas to the molar volume of it , if it were an ideal gas at that temperature and pressure .Reason : At high pressure all the gases have Z lt 1 and can be easily compressed .

1.	Assertion : Compressibility factor (Z) is the ratio of actual molar volume of a gas to the molar volume of it , if it were an ideal gas at that temperature and pressure .Reason : At high pressure all the gases have Z lt 1 and can be easily compressed .
Answer» If both assertion and REASON are true and reason is the CORRECT explanation of assertion . If both assertion and reason are true but reason is notthe correct explanation of assertion . If assertion is true but reason is false . If both assertion and reason are false . Solution :At high PRESSURE all the gases have Z gt 1 and are DIFFICULT to compress.
