The given graph represents the variations of compressibility factor `Z= pv//nRT` vs P for three real gases Which of the following statements is wrong?

Options

A. For gas A, a=0 and Z will linearly depend on pressure
B. For gas B, b=0 and Z will linearly depend on pressure
C. Gas C is a real gas and we can find ‘a’ and ‘b’ if intersection data is given
D. At high pressure, the slope is positive for all real

Answer

B

Explanation

Option (B) is incorrect statement because at high pressure slope of the line will change from negative to positive.
