Question

Answer please ,of this question.

Answer 1

(i) The compressibility factor (Z), also known as the compression factor or the gas deviation factor, is a correction factor which describes the deviation of a real gas from ideal gas behavior. ... It is a useful thermodynamic property for modifying the ideal gas law to account for the real gas behavior.

(ii) P = 5 x 106  Pa = 5 x 106 / 105 bar   n = 20   T = 300 K  R = 0.083 L bar K-1 mol-1   Vreal = 800 mL   Videal = nRT/P  Putting values , we have  Videal = 1004 mL   Z = Vreal/ Videal= 800/1004 = 0.796   As Z is less than 1, it means gas is more compressible under these conditions.

i hope this will help you
