This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement -I: The compressibility factor(Z) for H2and He is greater than unity, Z=1+(Pb)/(RT) Statement - II: Compressibility factor for H_2 and He may be calculated using van der Waals’ equation neglecting van der Waals’ constant ‘a’.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I: The van der Waals constant ‘a’ of H_2O is greater than that of C_6H_6. Statement - II: The intermolecular force of H_2O is greater than C_6H_6 due to formation of intermolecular hydrogen bond.
